[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , in this implementation scheme: An intelligent ventilation device for building construction projects includes a first fan 1. The air outlet end of the first fan 1 is connected to an air hood 2. A fixed frame 4 is installed on the inner wall of the air hood 2. A filter screen 7 is connected to the inner wall of the fixed frame 4 by bolts. The filter screen 7 can adopt an ESP filter plate to achieve efficient dust removal. Baffles 3 are arranged on both sides of the filter screen 7. Each group of baffles 3 is provided with multiple air outlet holes. On one side surface of the baffle 3 on the right side of the filter screen 7, multiple groups of air guide plates 5 are assembled in sequence from top to bottom at equal intervals. An installation box 6 is fixed on the top of the air hood 2. A second fan 13 is fixed to the inner wall of the installation box 6 by bolts.

[0026] In this embodiment, a fan frame is provided at the bottom of the first fan 1. The fan frame includes a bottom plate 9, a vertical plate 10 and a side plate 11. The vertical plate 10 is welded to the top of the bottom plate 9. The top of the vertical plate 10 is fixedly assembled with one side of the bottom of the first fan 1. The side plate 11 is fixed to the right side of the bottom plate 9. Two round holes are provided on the side plate 11. The fan frame is used to stably support the first fan 1 and, at the same time, cooperate with the two round holes to facilitate one end of the expansion bolt 12 to pass through, further facilitating the connection of the expansion bolt 12 to the wall surface.

[0027] In this embodiment, two sets of expansion bolts 12 are provided on the side plate 11. The side plate 11 is installed in cooperation with the wall through the two sets of expansion bolts 12. The round holes are nailed on the wall holes of the wall, realizing the installation of the fan frame and the wall, facilitating the installation of the first fan 1 outdoors. Wall holes are drilled on the wall, and the air hood 2 and the installation box 6 are in sealing cooperation with the wall holes.

[0028] In this embodiment, circulation ports are provided on both sides of the installation box 6. The air inlet and outlet ends of the second fan 13 communicate with the inside and outside of the house through the circulation ports respectively.

[0029] In this embodiment, multiple groups of air guide plates 5 are all inclined towards the ground. An air outlet channel 8 is formed between every two adjacent air guide plates 5. The filtered gas finally flows into the room through the multiple groups of air outlet channels 8. The indoor air can be exchanged through the cross-circulation of indoor and outdoor air. The second fan 13 is arranged above the first fan 1. The gas enters the room through the multiple groups of air outlet channels, prolonging the residence time of the outside gas in the room, facilitating the fresh air to enter every corner of the room, and improving the ventilation effect. An air quality sensor and a single-chip microcomputer controller are installed on the top wall of the installation box 6 on the right side of the second fan 13. The air quality sensor, the first fan 1 and the second fan 13 are all electrically connected to the single-chip microcomputer controller. The single-chip microcomputer controller controls the operation of the first fan 1 and the second fan 13 respectively according to the signals received by the air quality sensor. An external power supply terminal is also provided outside the single-chip microcomputer control module, which can start the first fan 1 and the second fan 13 to adjust the air volume and time according to the scenario, reducing a certain amount of resource waste and realizing intelligent ventilation.

[0030] In this embodiment, the number of multiple groups of air guide plates 5 is 4 - 20 groups. The number of air guide plates 5 can be adjusted according to actual needs, so as to adjust the number of air outlet channels 8 and facilitate the improvement of the air outlet experience.

[0031] In this embodiment, the first fan 1 is a turbo fan, and the second fan 13 is an axial flow fan. Generally, the wind force of the turbo is larger than that of the axial flow, so that the first fan 1 can quickly suck the outside gas into the room. The suction of the second fan 13 is less than that of the first fan , and the second fan 13 slowly discharges the indoor air to prolong the residence time of the fresh air in the room, enabling the fresh air to be fully distributed in the room and improving the ventilation effect.

[0032] Working principle and usage process of the utility model: When using this device, first start the first fan 1 and the second fan 13. When the first fan 1 works, it blows the gas outside the house towards the air hood 2, and through multiple air holes on the baffle 3, it blows towards the filter screen 7. The filter screen 7 filters the dust in the air. The filtered gas finally flows into the room through multiple air outlet channels 8. The ventilation of the indoor air can be realized through the cross-flow of indoor and outdoor air, solving the problem of indoor ventilation and air change. Multiple air guide plates 5 are arranged facing the ground to prevent the air entering the room from being quickly taken out of the room by the second fan 13, extending the residence time of the outside gas in the room, facilitating the fresh air to enter every corner of the room, and improving the ventilation effect. When the second fan 13 works, it sucks the indoor air out of the room, realizing the circulation of the indoor air to adjust the air in the indoor environment.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
