Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in 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 work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution:

a ventilating duct with a dust removal filtering mechanism comprises a duct body 1, wherein a filtering screen 2 is connected inside the duct body 1 in a sliding mode, a push-pull rod 3 is connected inside the duct body 1 and located on one side of the filtering screen 2 in a sliding mode, the top of the push-pull rod 3 is fixedly connected with a shell 4, a movable rod 5 is connected inside the shell 4 in a sliding mode, one end of the movable rod 5 is fixedly connected with a brush plate 6, and the filtering screen 2 is automatically cleaned through the brush plate 6; a limiting plate 7 is fixedly connected to the outside of the movable rod 5, a tension spring 8 is sleeved outside the movable rod 5 and between the limiting plate 7 and the shell 4, one end of the tension spring 8 is fixedly connected with the limiting plate 7, the other end of the tension spring 8 is fixedly connected with the shell 4, a first sliding plate 9 is slidably connected to the inside of the shell 4, a chute 10 is formed in the movable rod 5, a sliding rod 11 is slidably connected to the inside of the chute 10, the sliding rod 11 is fixedly connected with the first sliding plate 9, and under the action of the chute 10 and the sliding rod 11, the movable rod 5 and the brush plate 6 on the movable rod 5 can be driven by the first sliding plate 9 to move towards the direction away from the filter screen 2, so that the upward movement of the brush plate 6 is facilitated; the inside sliding connection of casing 4 has second slide 12, fixedly connected with spring 13 between second slide 12 and the casing 4, the outside of second slide 12 and the below fixedly connected with fixed plate 14 that is located movable rod 5, the top fixedly connected with fixture block 15 of fixed plate 14, draw-in groove 16 that uses with fixture block 15 cooperation is seted up to the bottom of movable rod 5, under the effect of fixture block 15 and draw-in groove 16, can prescribe a limit to the position of brush board 6.

A sewage discharge pipe 17 is fixedly connected to the bottom of the pipeline body 1 and positioned between the push-pull rod 3 and the filter screen 2, and an end cover 18 is movably connected to the outer part of the sewage discharge pipe 17 and used for collecting dust cleaned by the brush plate 6; an anti-skidding sleeve 19 is sleeved outside the push-pull rod 3, the anti-skidding sleeve 19 is fixedly connected with the push-pull rod 3, the comfort and the friction between the push-pull rod 3 and a hand are improved, and the push-pull rod 3 is conveniently pushed and pulled; the movable rod 5, the first sliding plate 9 and the second sliding plate 12 are all of square structures, so that a limiting effect is achieved, and the situation of torsion dislocation is prevented; the outer portion of the push-pull rod 3 is sleeved with a sealing ring 20, the sealing ring 20 is fixedly connected with the pipeline body 1, and the push-pull rod 3 is in sliding connection with the sealing ring 20, so that the sealing function is achieved on one hand, and the position of the push-pull rod 3 can be limited on the other hand.

Specifically, when the utility model is used, the filter screen 2 needs to be cleaned up, only the push-pull rod 3 below the pipeline body 1 is pushed and pulled up and down in a reciprocating manner, so that the push-pull rod 3 drives the brush plate 6 to clean the filter screen 2 through the shell 4, when the first sliding plate 9 below the shell 4 is tightly propped against the inner wall of the pipeline body 1, the brush plate 6 is driven by the movable rod 5 to move towards the direction away from the filter screen 2 under the action of the chute 10 and the slide rod 11 until the brush plate 6 is separated from the filter screen 2 until the clamping groove 16 on the movable rod 5 moves to the position right above the clamping block 15, at the moment, under the elastic action of the spring 13, the second sliding plate 12 drives the clamping block 15 to be combined with the clamping groove 16 through the fixed plate 14, thereby inject the position of movable rod 5 and brush board 6, when making push-and-pull rod 3 drive casing 4 and brush board 6 rebound, brush board 6 can not clean filter screen 2, prevent that brush board 6 from upwards cleaning the condition of raise dust when filter screen 2 appears, the effect of cleaning is influenced, when casing 4 rebound to second slide 12 and the inner wall of pipeline body 1 support tightly, continue to move up and can make fixture block 15 break away from with draw-in groove 16, at this moment under the pulling force effect of extension spring 8 movable rod 5 can drive brush board 6 and support tightly once more with filter screen 2, pull push-and-pull rod 3 downwards afterwards, make push-and-pull rod 3 drive casing 4 and brush board 6 rebound, make brush board 6 clean the dust on the filter screen 2, and drop in blow off pipe 17.
