Description

Technical Field

[0001] This utility model relates to the field of building ventilation equipment technology, and in particular to a building intelligent ventilation device. Background Technology

[0002] Intelligent buildings refer to buildings that optimize the combination of structure, systems, services, and management according to user needs, thereby providing users with an efficient, comfortable, and convenient humanized building environment. In intelligent buildings, ventilation systems are widely used. During long-term use, dust from the outside air will enter the building with the airflow, and a large amount of dust will also accumulate inside the ventilation ducts. For example, Chinese patent CN214665011 U describes a dust filter cleaning structure. When cleaning the dust filter is needed, the output shaft of a second motor drives a mounting plate to rotate, causing the mounting plate to move a cleaning roller along the surface of the dust filter. However, when the device is not in use, dust can still enter.

[0003] Therefore, in order to address the above problems, an intelligent building ventilation device is proposed. Utility Model Content

[0006] When ventilation is needed inside the building, the fan starts, multiple baffles open, and outside air enters through the air inlet and exits through the air outlet, ventilating the interior of the building and improving air exchange efficiency. When ventilation stops, the multiple baffles close to reduce dust entering the building's outer shell.

[0007] Preferably, the air outlet includes a mounting frame, which is connected to the outer casing by a first mounting bolt. A first dustproof net is installed inside the mounting frame, and multiple baffles are installed on the outside of the mounting frame.

[0008] The first dustproof net installed inside the frame serves to prevent dust from entering the building during ventilation.

[0009] Preferably, a mounting platform is provided on the outside of the mounting frame, and multiple connecting shafts are rotatably arranged inside the mounting platform, with baffles provided on the connecting shafts.

[0010] The baffles are rotatably mounted inside the mounting platform via a connecting shaft, facilitating the closing and opening of multiple baffles.

[0011] Preferably, a rotating shaft is provided on the connecting shaft, the rotating shaft extends out of the mounting platform, a boss is provided on the rotating shaft, a limiting shaft is provided on the boss, the axis of the limiting shaft is parallel to the axis of the rotating shaft, and the limiting shaft slides in the groove of the limiting plate, the groove being arc-shaped.

[0012] The limiting shaft slides within the slide groove, and drives the rotating shaft to rotate via the boss, which in turn drives the connecting shaft to rotate, controlling the opening and closing of the baffle. Multiple slide grooves are provided on the limiting plate, simultaneously controlling the opening and closing of multiple baffles.

[0013] Preferably, both the upper and lower ends of the limiting plate are set inside the guide rail, which is located outside the mounting platform. The limiting plate is connected to the electric push rod, which is set on the mounting frame.

[0014] Both the upper and lower ends of the limiting plate are limited by sliding grooves to prevent the limiting plate from detaching. The limiting plate is moved by an electric push rod, thereby controlling the opening and closing of the limiting plate.

[0015] Preferably, the air inlet includes an outer tube with a rainproof tube installed on it. The rainproof tube is bent and its opening faces downward. Multiple connecting plates are installed on the rainproof tube, and the connecting plates are connected to the rainproof tube and the outer tube respectively by a second mounting bolt. A second dustproof net is installed inside the outer tube.

[0016] The rainproof pipe has its opening facing downwards to reduce rainwater ingress during rainy days. The outer pipe has a second dustproof screen to reduce dust entering the casing. The rainproof pipe is connected by multiple connecting plates and multiple second mounting bolts, making it detachable and allowing for regular cleaning.

[0017] As a preferred option, multiple positioning platforms are provided inside the outer casing, and fans are installed on the positioning platforms.

[0018] Multiple fans increase airflow, enabling faster ventilation within the building.

[0019] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0020] When ventilation is required inside the building, the fan starts, multiple baffles open, and outside air enters from the air inlet and is blown out from the air outlet, ventilating the interior of the building and improving air exchange efficiency. When ventilation stops, multiple baffles close to reduce dust entering the building's outer shell.

[0030] like Figures 1 to 5 As shown, a building intelligent ventilation device includes a housing 1, which includes an air inlet and an air outlet. Multiple movable baffles 2 are installed on the air outlet. Both the air inlet and outlet are equipped with dustproof structures. A fan 3 is installed inside the housing 1. When ventilation is required inside the building, the fan 3 starts, the multiple baffles 2 open, and outside air enters through the air inlet and exits through the air outlet, ventilating the building interior and improving air exchange efficiency. When ventilation stops, the multiple baffles 2 close, reducing the amount of dust entering the housing 1.

[0031] The air outlet includes a mounting frame 4, which is connected to the outer casing 1 by a first mounting bolt 5. A first dustproof net 6 is installed inside the mounting frame 4, and multiple baffles 2 are installed on the outside of the mounting frame 4. The first dustproof net 6 installed inside the mounting frame 4 serves to prevent dust from entering the building during ventilation.

[0032] A mounting platform 7 is provided on the outer side of the mounting frame 4. Multiple connecting shafts 8 are rotatably mounted inside the mounting platform 7, and baffles 2 are mounted on the connecting shafts 8. The baffles 2 are rotatably mounted inside the mounting platform 7 via the connecting shafts 8, facilitating the closing and opening of the multiple baffles 2.

[0033] A rotating shaft 9 is mounted on the connecting shaft 8, extending out of the mounting platform 7. A boss 10 is mounted on the rotating shaft 9, and a limiting shaft 11 is mounted on the boss 10. The axis of the limiting shaft 11 is parallel to the axis of the rotating shaft 9. The limiting shaft 11 slides within a groove 13 of the limiting plate 12, and the groove 13 is arc-shaped. The limiting shaft 11 slides within the groove 13, driving the rotating shaft 9 to rotate via the boss 10, which in turn drives the connecting shaft 8 to rotate, controlling the opening and closing of the baffle 2. Multiple grooves 13 are provided on the limiting plate 12, simultaneously controlling the opening and closing of multiple baffles 2.

[0034] The upper and lower ends of the limiting plate 12 are both set inside the guide rail 14, which is located outside the mounting platform 7. The limiting plate 12 is connected to the electric push rod 15, which is set on the mounting frame 4. The upper and lower ends of the limiting plate 12 are limited by the sliding groove 13 to prevent the limiting plate 12 from disengaging. The electric push rod 15 drives the limiting plate 12 to move, thereby controlling the opening and closing of the limiting plate 12.

[0035] The air inlet includes an outer tube 16, on which a rainproof tube 17 is installed. The rainproof tube 17 is bent, with its opening facing downwards. Multiple connecting plates 18 are installed on the rainproof tube 17, and the connecting plates 18 are connected to the rainproof tube 17 and the outer tube 16 respectively by second mounting bolts 21. A second dustproof mesh 19 is installed inside the outer tube 16. The downward-facing opening of the rainproof tube 17 reduces the amount of rainwater entering through the opening on rainy days. The second dustproof mesh 19 on the outer tube 16 reduces the amount of dust entering the outer casing 1. The rainproof tube 17 is connected by multiple connecting plates 18 and multiple second mounting bolts 21, making it detachable and allowing for regular cleaning.

[0036] Multiple positioning platforms 20 are installed inside the outer casing 1, and fans 3 are installed on the positioning platforms 20. The multiple fans 3 increase the air volume and ventilate the building more quickly.

[0037] Working principle: When ventilation is required in the building, the electric push rod 15 is activated, which moves the limiting plate 12. The sliding groove 13 on the limiting plate 12 moves the limiting shaft 11, which in turn drives the connecting shaft 8 to rotate through the boss 10. The connecting shaft 8 drives the baffle 2 to rotate, opening the baffle 2 and starting the fan 3 to introduce outside air into the building.

[0038] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
