[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] See also Figure 1-4 As shown, the utility model is a ventilation device for green buildings, which includes a main duct 1 for air intake. When in use, the main duct 1 is controlled to pass through an opening arranged on the wall, and a filter component 2, a vibration structure and a ventilation fan 10 are arranged in sequence in the main duct 1 along the airflow direction. The main duct 1 located on one side of the filter component 2 is connected to a dust recovery duct 11; when started, the ventilation fan 10, as a power source, inhales external air from one end of the main duct 1, and after being filtered by the filter component 2, discharges it into the room from the other end of the main duct 1; the dust, debris, etc. in the air are filtered by the filter component 2, and the filtered residue falls into the dust recovery duct 11.

[0029] Specifically, Figure 5The filter assembly 2 includes a mesh plate 21 which is mounted on a mounting ring A20 on the inner wall of the main pipe 1, and a filter screen 23 is covered on the outer side of the mesh plate 21; the vibration structure includes a mounting frame 15 which is arranged on the inner wall of the main pipe 1, and one side of the mounting frame 15 is connected to a movable frame 16 which extends outward and hits the filter assembly 2 through at least three elastic telescopic parts; when in use, the vibration structure can be controlled to impact the filter assembly 2 several times at an interval according to actual needs, so that the filter residues enriched on the filter screen 23 are shaken off the filter screen 23.

[0030] Of course, in order to avoid damage to the filter 23 after a rigid impact, one side of the mesh plate 21 of the present application is connected to the mounting ring A20 through a reset spring B25, and a guide hole 26 is provided on the mounting ring A20. One side of the mesh plate 21 is connected to a guide rod 24 that is movable through the guide hole 26; that is, when the vibration structure is used to impact the filter assembly 2, the movable frame 16 of the vibration structure will hit the guide rod 24 after extending, and the mesh plate 21 will extend at this time. At this time, after the movable frame 16 contracts, the mesh plate 21 returns to its initial position under the action of the reset spring B25 and shakes again.

[0031] At the same time, in order to ensure the sealing and prevent the gas from being sucked into the room through the gap between the mesh plate 21 and the main pipeline 1, in this technical solution, a sealing fin 22 that slides along the inner wall of the main pipeline 1 is provided on the peripheral side of the mesh plate 21. The sealing fin 22 is made of rubber and has a cross-section of an isosceles triangle or an isosceles trapezoid.

[0032] On the basis of the above, the elastic telescopic part provided in the present application includes an inner sleeve and an outer sleeve which are socketed with each other, and the inner sleeve and the outer sleeve are connected with a return spring A; when in use, the elastic telescopic part is connected to the air supply system, and the air supply system is used to control the elastic telescopic part to extend and retract.

[0033] Specifically, the inner wall of the main pipe 1 is provided with a mounting ring B14 for mounting the ventilation fan 10; the outer peripheral side wall of the main pipe 1 is provided with a fixing ring 12, and the fixing ring 12 is provided with a fixing hole A13; the bottom end of the dust recovery pipe 11 is provided with an end cover 110.

[0034] Specifically, during installation, the main pipe 1 is controlled to be provided with a ventilation fan 10 that passes through an opening arranged on the wall until the fixing ring 12 abuts against the outer wall of the wall; then a support ring 18 is sleeved on the outside of one end of the main pipe 1 located indoors, and the support ring 18 is controlled to abut against the inner wall of the wall.

[0035] like Figure 6 The support ring 18 includes a ring body 180 , an inner side wall of the ring body 180 is provided with an annular rubber ring 181 , and a fixing hole B182 is provided on the ring body 180 .
