Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The embodiment is basically as shown in the attached figure 1: the utility model provides a fire door is prevented to steel with function of discharging fume, includes door frame 1, installs the fire door is prevented to steel 2 and the case 3 of discharging fume in the door frame 1, can be when the conflagration breaing out through the case 3 of discharging fume, with indoor dense smoke and the timely extraction of poison gas, and then can reduce indoor dense smoke and the content of poison gas to for the victim has won the valuable rescue time.

In this embodiment, as shown in fig. 2, when smoke is exhausted, a victim rotates two elliptical sleeves 20 at the first time, so that the two oval sleeves 20 correspond to the oval holes 19, and the cover plate 10 is locked in contact, under the action of the tensile force of the two springs 18, the filter cartridge 8 can move out of the smoke exhaust box 3, at the same time, the cover plate 10 can be driven to move, and at the same time, the motor 5 can be started, so that the motor 5 drives the rotating shaft 6 to rotate, thereby leading the rotating shaft 6 to drive the plurality of fan blades 7 to rotate, further extracting dense smoke and toxic gas, meanwhile, the rotating shaft 6 rotates to drive the driving rod 13 to rotate, the driving rod 13 rotates to drive the driving shaft 11 to rotate, the driving shaft 11 rotates to drive the linkage rod 25 to move through the annular groove 26, so that the linkage rod 25 can drive the cleaning frame 24 to move, and the cleaning frame 24 can clean the filter cartridge 8.

In this embodiment, as shown in fig. 3, when the cleaning frame 24 moves, the cleaning frame 24 drives the two moving blocks 28 to move, and the two moving blocks 28 move in the two moving grooves 27, so that the cleaning frame 24 is limited and can only move horizontally, and therefore the cleaning frame 24 can clean the filter cartridge 8 through the movement of the plurality of bristles, and further, the filter cartridge 8 can be ensured to be smooth.

In this embodiment, as shown in fig. 4, when the elliptical sleeve 20 rotates, the elliptical sleeve 20 rotates on the stopper 21, and then the elliptical sleeve 20 can be limited to rotate only, after the cover plate 10 is unlocked, because the previous spring 18 is in a compressed state, under the action of the tensile force of the two springs 18, the two springs 18 drive the two sliders 15 to move, the two sliders 15 respectively slide on the two slide bars 17 through the slide holes 16, and then the two sliders 15 drive the filter cartridge 8 to move, and the filter cartridge 8 drives the cover plate 10 to move, so that the filter cartridge 8 moves out of the smoke exhaust box 3, and further impurities in the dense smoke can be filtered.

The specific implementation is as follows:

when a fire disaster occurs, firstly, the two elliptical sleeves 20 can be rotated, so that the two elliptical sleeves 20 correspond to the two elliptical holes 19, and then the cover plate 10 is in contact locking, because the two springs 18 are both in a compressed state before, after the cover plate 10 is unlocked, the two springs 18 push against the two sliding blocks 15 to move, the two sliding blocks 15 respectively slide on the two sliding rods 17 through the sliding holes 16, and then the two sliding blocks 15 drive the filter cartridge 8 to move, the filter cartridge 8 drives the cover plate 10 to move, so that the filter cartridge 8 moves out of the smoke exhaust box 3, meanwhile, the motor 5 is started, so that the rotating shaft 6 drives the plurality of fan blades 7 to rotate, so that air is pumped out, meanwhile, the air can be filtered by the filter cartridge 8, and then impurities such as ash produced by the fire disaster can be effectively blocked, and meanwhile, when the rotating shaft 6 rotates, drive the drive shaft 11 through drive pole 13 and rotate, drive shaft 11 and rotate and drive gangbar 25 through ring channel 26 and remove, and then make gangbar 25 drive clean frame 24 and remove, and then make clean frame 24 clear up a plurality of filtration pores 9 through many brush hairs, and then can effectually avoid the jam of filtration pore 9, discharge that can effectual assurance flue gas can be normal.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
