In the use process of the air inducing mechanism 100, the air inlet fan 41 is started to introduce outside fresh air into the air inlet straight pipe 31, then the air flow directly impacts the filter layer 328 through the air inducing hose 42, most of the air flow enters the room after being filtered by the filter layer 328, and a small part of the air flow enters the room along the centrifugal pipeline 32 from the air leakage gap after being reflected by the filter layer 328. The old air in the room is exhausted out of the room through the exhaust device, so that better air quality is always kept in the room. And the positive pressure in the room is kept, so that the external unfiltered airflow is not easy to enter the room from the gap. Because in the new trend system, filter layer 328 is relative the axis slope setting of air inlet straight tube 31, rather than relative air inlet straight tube 31 sets up perpendicularly, has consequently reduced the air inlet windage of air inlet stream.
For example, in order to facilitate installation of the air inducing hose 42, one end of the air inducing hose 42 is formed with a conical cylinder section, and the other end is formed with a discharge section, and the periphery of the conical cylinder section is fixed on the inner side wall of the air inlet straight pipe 31. The conical section faces the air intake fan 41, the discharge section faces the filter layer 328, and the air leakage gap is formed between the filter layer 328 and the discharge section.

For example, the first included angle is 110-. By arranging the centrifugal pipeline 32 and arranging the snap ring in the straight pipe section 321, the air inducing hose 42 can be conveniently clamped by the snap ring so as to fix the middle part of the air inducing hose 42.
For example, it is particularly important to refer to fig. 4 and 5 together, in order to maintain a stable intake air pressure, i.e. when the intake air pressure is large, the intake air flow rate is increased. When the air inlet pressure is small, the air inlet flow is reduced, the filtering layer 328 is provided with an elastic mesh 45, one side of the elastic mesh 45 is connected to one side edge of the filtering layer 328, and the other side of the elastic mesh is far away from the other side edge of the filtering layer 328. The elastic net sheet 45 is arranged on one side of the filter layer 328 in a blocking manner, and an included angle is formed between the elastic net sheet and the filter layer 328. The elastic net piece 45 is provided with a plurality of meshes 451, and the diameters of the meshes 451 are all 3-4 mm. The elastic net piece 45 is provided with a filter net piece, and the filter net piece is completely attached and fixed on the elastic net piece 45. The diameter of the meshes of the filter mesh sheet is smaller than the diameter of the meshes 451 of the elastic mesh sheet 45. The filter mesh elastically abuts against the end of the discharge section of the induced draft hose 42. When the wind force of the air inducing hose 42 is large, the filter mesh deflects toward the filter layer 328 due to the force, and when the wind force of the air inducing hose 42 is small, the filter mesh returns to the original position under the action of the elastic restoring force and abuts against the end of the air inducing hose 42 to block the air inducing hose 42. For example, the elastic mesh sheet 45 is provided at its periphery with a plurality of elastic pulling strings each connected to the periphery of the discharge section of the air-inducing hose 42. When the wind force of the induced draft hose 42 is reduced, the elastic pull ropes can increase the elastic force of the elastic mesh sheet 45, so that the elastic mesh sheet 45 is restored to the original position. Through elastic mesh 45 with filter screen's setting can keep comparatively stable inlet air pressure in induced air hose 42 to the adaptation wind pressure.
For example, in order to adjust the wind direction of the intake air according to the intake air flow, a flexible deformation pipe 327 (see fig. 2) is disposed at an end of the bending section 322 of the centrifugal duct 32, the flexible deformation pipe 327 extends obliquely toward the ground, a communication hole is disposed in the middle of the filter layer 328, a linkage rod 324 is disposed in the communication hole, the linkage rod 324 movably penetrates through the communication hole, one end of the linkage rod 324 is connected to the tail end of the flexible deformation pipe 327, and the other end of the linkage rod 324 is connected to the lower portion of the elastic mesh sheet 45. The linkage rod 324 is obliquely arranged relative to the ground and comprises an upper end 3241 and a lower end 3244 which are oppositely arranged, the upper end 3241 is connected to the flexible deformation tube 327, and the lower end 3244 is connected to the upper edge of the elastic net piece 45. The upper end 3241 is connected with the lower end 3244 in a bending manner, the lower end 3244 extends obliquely downwards to the filter layer 328, and the upper end 3241 extends obliquely upwards from the filter layer 328 to the flexible deformation tube 327. When the air volume is large, the elastic net piece 45 is driven to bend towards the filter layer 328, so as to drive the linkage rod 324 to protrude outwards, and the linkage rod 324 extrudes the side wall of the communication hole to deform, so that the linkage rod 324 rotates. The linkage rod 324 synchronously rotates while protruding outwards under the support of the elastic mesh sheet 45, so that the upper end 3241 lifts the tail end of the flexible deformation pipe 327 and rises, and a large air flow in the flexible deformation pipe 327 flows out upwards in an inclined manner, so that the air flow is prevented from flowing out downwards in an inclined manner, and the face and the body of a user are blown with discomfort. When the wind volume becomes smaller, the linkage rod 324 rotates and contracts into the centrifugal pipeline 32, so as to drive the flexible deformation pipe 327 to restore to the downward direction, and drive breeze to blow the face of a person, thereby improving the use feeling. Through setting up the gangbar 324, can change the direction of air inlet according to the air inlet flow to improve and use experience.
For example, in order to facilitate the arrangement of the linkage rod 324, a sleeving member 329 is arranged in the communication hole, the sleeving member 329 includes a middle pipe and two bending disks 3291, the middle pipe is inserted into the communication hole, the two bending disks 3291 are coaxially fixed at two opposite ends of the middle pipe respectively and are clamped at two opposite sides of the filter layer 328 respectively, and the linkage rod 324 is inserted into the middle pipe and is rotatably connected to a side wall of the middle pipe. The two bent wafers 3291 are attached to the filter layer 328, and the periphery of the bent wafer 3291 is bent towards one side of the air inlet fan 41. In the process of transverse movement or rotation of the linkage rod 324, the sleeving piece 329 is forced to move and outwards abuts against the filter layer 328 to deform, so that the middle part of the filter layer 328 protrudes towards the indoor, the filter meshes 451 in the middle part of the filter layer 328 are driven to be opened, and the exhaust air volume is increased to adapt to the air inlet flow. A rotation stopping structure is arranged in the middle pipe and used for limiting the linkage rod 324 to rotate around the axis of the linkage rod.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
