[0003] However, existing ventilation devices generally do not have fresh air filtration components, and the extracted fresh air may carry some dust, affecting the quality of the incoming fresh air. There is also a type of ventilation duct with a filter plate installed in the existing technology, but in actual use, the filter holes on the filter plate in the ventilation duct are easily blocked by dust and impurities. The blocked filter plate may reduce the air intake and affect the ventilation efficiency. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1:

[0029] Reference Figures 1-4 A green building energy-saving and emission-reducing ventilation device includes an air inlet duct 3 and an air outlet duct 2 fixedly connected to both sides of a fan duct 1. A mounting plate 101 is fixedly connected to the fan duct 1, and a drive motor 4 with blades 401 is connected to the mounting plate 101. The device also includes:

[0030] The first filter plate 301 is fixedly connected in the air inlet duct 3;

[0031] The second filter plate 201 is detachably connected to the air outlet duct 2;

[0032] The mesh diameter of the first filter plate 301 is larger than that of the second filter plate 201;

[0033] In practical use, the first filter plate 301 in the air inlet duct 3 filters large particulate impurities, and the second filter plate 201 in the air outlet duct 2 filters small particulate impurities; through multi-stage filtration, the dust in the exhaust fresh air can be effectively reduced, and the ventilation effect can be improved.

[0034] A drive rod 6 is fixedly connected to the drive end of the drive motor 4, and a drive block 602 is slidably connected in the drive rod 6;

[0035] A rotating rod 601 is fixedly connected to the drive block 602, and a striking wheel 5 is rotatably connected to the end of the rotating rod 601 away from the drive block 602.

[0036] The striking wheel 5 abuts against the first filter plate 301;

[0037] An arc-shaped limiting plate 3011 is fixedly connected to the first filter plate 301. When the rotating rod 601 drives the striking wheel 5 to rotate, the striking wheel 5 is in contact with the arc-shaped limiting plate 3011.

[0038] A spring 603 is fixedly connected to the drive rod 6, and the spring 603 is fixedly connected to the drive block 602.

[0039] Reference Figure 5 The drive block 602 can be quickly reset by means of the spring 603 installed in the drive rod 6.

[0040] A limiting block 202 is fixedly connected to the inner wall of the air outlet duct 2, and the second filter plate 201 abuts against the limiting block 202.

[0041] Reference Figure 3 In actual use, the drive motor 4 drives the blades 401 to rotate, thereby drawing in fresh air through the air inlet duct 3 and then expelling the drawn fresh air through the air outlet duct 2.

[0042] Reference Figures 5-7 When the drive motor 4 is working, it also drives the drive rod 6 connected to its drive end to rotate. The rotation of the drive rod 6 will drive the drive block 602 to rotate synchronously, which in turn drives the rotating rod 601 and the striking wheel 5 to rotate. After rotating a certain angle, the striking wheel 5 will contact the arc-shaped limiting plate 3011. At this time, under the limiting and pressing of the arc-shaped limiting plate 3011, the striking wheel 5 will roll and slide along the arc surface of the arc-shaped limiting plate 3011. At this time, the drive block 602 will slide synchronously in the drive rod 6. The spring 603 is compressed, and after the striking wheel 5 rolls a certain distance, it will move to the top of the arc-shaped limiting plate 3011. When the drive rod 6 rotates again, the striking wheel 5 will fall off the arc-shaped limiting plate 3011 under the restoring force of the spring 603. After falling, it will instantly impact the first filter plate 301. Under the impact of the striking wheel 5, some of the dust and impurities attached to the first filter plate 301 will be shaken off, thus effectively solving the problem of dust accumulating layer by layer and easily clogging the filter holes.

[0043] In practice, staff can manually collect and remove the dust and impurities that are shaken off after a period of time.

[0044] A first magnet 2021 is fixedly connected to the limiting block 202, and a second magnet 2011 is fixedly connected to the second filter plate 201. The first magnet 2021 and the second magnet 2011 attract each other.

[0045] Reference Figure 6 , Figure 7 The installation stability of the second filter plate 201 can be improved by the attraction between the first magnet 2021 and the second magnet 2011.

[0046] By setting the second filter plate 201 as a detachable filter plate, it is easier for users to manually disassemble and clean the filter plate in the air outlet duct 2, thereby reducing the possibility of the second filter plate 201 being blocked by small particulate impurities and improving the air outlet effect.

[0047] Reference Figure 5In practice, an anti-slip pad 501 is fixedly connected to the striking wheel 5.

[0048] It should be noted that the anti-slip mat 501 is a silicone mat.

[0049] By setting the anti-slip pad 501 on the striking wheel 5, the friction between the striking wheel 5 and the first filter plate 301 can be increased, thereby enabling the striking wheel 5 to rotate stably; at the same time, by setting the anti-slip pad 501 as a silicone pad, when the striking wheel 5 falls from the arc-shaped limiting plate 3011, it will not make excessive noise.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
