DETAILED DESCRIPTION

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0018] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] The utility model provides a smoke and fire extinguishing device for fire fighting, such as Figure 1-4 As shown, it comprises: a water tank 1, a fixed box 2 is fixedly connected to the top of the water tank 1, a rotating bracket 3 is arranged on the top of the fixed box 2, a wind tube 4 is rotatably connected inside the rotating bracket 3, and a fan 5 is fixedly connected inside the wind tube 4; a replaceable filter element 6 is arranged at one end of the wind tube 4, six ball grooves are evenly arranged near the filter element 6 of the wind tube 4, steel balls 7 are arranged inside the ball grooves, an extrusion cylinder 8 is slidably connected to the wind tube 4 near the steel balls 7, a clamping groove 9 is arranged near the steel balls 7 of the filter element 6, and a movable groove 10 is arranged on the inner surface of the extrusion cylinder 8, and the clamping groove 9 and the movable groove 10 are both adapted to the steel balls 7; an elastic mechanism 11 for controlling the sliding of the extrusion cylinder 8 is arranged on the outer surface of the extrusion cylinder 8; a rotating mechanism 12 for controlling the wind tube 4 to perform multi-angle smoke elimination is arranged inside the fixed box 2.

[0020] It should be noted that, when the fan 5 is started, the fan 5 draws the smoke into the interior of the air duct 4, and then the smoke is discharged after being filtered by the filter element 6. When the filter element 6 filters the smoke for a long time, the user can control the extrusion cylinder 8 to slide through the elastic mechanism 11, so that the movable groove 10 on the extrusion cylinder 8 moves to the ball groove to increase the movable range of the steel ball 7. Then the user pulls out the filter element 6 from the interior of the air duct 4 and replaces it with a new filter element 6. The user releases the elastic mechanism 11 and the extrusion cylinder 8 is reset at the same time. While the extrusion cylinder 8 is reset, the steel ball 7 is squeezed, so that a small part of the steel ball 7 moves to the inside of the card slot 9 of the filter element 6, and then the new filter element 6 is fixed. When the filter element 6 filters the smoke for a long time, the user can quickly replace the filter element 6, thereby improving the smoke elimination effect. This solves the problem that although the current smoke elimination and fire extinguishing device can associate the smoke exhaust mechanism with the water spray mechanism, it does not have a replaceable filtering device, so that the filtering effect of the filtering device itself becomes poor when the filter element filters the smoke for a long time, resulting in a reduced smoke elimination effect.

[0022] In this embodiment, the user can control the extrusion cylinder 8 to slide by pulling the force ring 14, which drives the connecting ring 13, and the connecting ring 13 drives the extrusion cylinder 8. By loosening the force ring 14, the spring 16 generates elastic recovery to push the extrusion cylinder 8, thereby controlling the extrusion cylinder 8 to reset.
