Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building ventilation assembly devices, in particular to a building ventilation assembly structure. Background Art
[0002] Prefabricated buildings are buildings that are assembled directly on site from prefabricated parts. With the development of modern industry and technology, houses can be mass-produced like machine production, which greatly saves the workload of construction workers. With the improvement of prefabricated buildings, prefabricated houses of various styles are available for selection. The ventilation structure is a structure that exchanges the air inside and outside the building, discharges the dirty air in the building, and keeps the indoor air fresh. The ventilation structure is beneficial to the health of indoor personnel. Existing prefabricated buildings do not have special ventilation structures. The ventilation structure generally has only simple vents, and the ventilation efficiency is low. At the same time, no filtering device is provided, and the cleanliness and safety of the outside air cannot be guaranteed. The vents also easily allow pollutants such as catkins and dust to enter the room. For this reason, the utility model proposes a ventilation structure for prefabricated buildings.
[0003] For example, a prefabricated building ventilation structure with publication number CN212898231U includes a ventilation window shell, a filter box and a motor, wherein the ventilation window shell is rectangular, and a rectangular opening matching the ventilation window shell is arranged on the wall of the prefabricated building, the middle position of the ventilation window shell is fixedly connected to the prefabricated building at the opening, the ventilation window shell is partially located outdoors and partially located indoors, a shutter is arranged on the outdoor portion of the ventilation window shell, the shutter is located at the opening of the ventilation window shell, two sliding grooves are arranged on the ventilation window shell, a filter box is installed between the two sliding grooves, the filter box is rectangular, two locking structures are arranged at one end of the filter box, a baffle is arranged on the end of the filter box opposite to the locking structure, and two locking grooves are arranged on the surface of the ventilation window shell perpendicular to the filter box.
[0004] The above device facilitates the replacement of the filter element in the filter box by adding a locking structure and a locking groove; facilitates the installation and disassembly of the filter box by adding a sliding part and a sliding groove; is beneficial to the ventilation of the prefabricated building by adding a fan; and can prevent pollutants from entering the ventilation structure by adding shutters. However, the device is driven by a motor in the assembly and the filter layer is only set at one end. Long-term erosion will result in an extremely short life of the motor and the shutter. In addition, once the power is disconnected, the ventilation of the device will be directly paralyzed, and the required requirements are relatively higher. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. Compared with other building ventilation assembly structures, this device uses a larger opening at the front end leading to the internal filter, so that the air flow can be accelerated during the air circulation process, and a rolling leaf fan is placed in the center of the internal filter. The air flow is used to make the rolling leaf fan rotate in the direction of the wind. The rotating shaft placed inside greatly reduces friction, so that the rotation can be continuous and the power required is small. The rotation of the rolling leaf fan can be driven by the original air circulation.
[0014] 2. The device installs filter plates with activated carbon as the main filter material at the front and rear ends of the rolling leaf fan.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0022] See also Figures 1 to 5 The utility model provides a technical solution: a building ventilation assembly structure, including a rectangular duct 2 and an external duct 1, the external duct 1 is set to a shape that the lower end is tightly fitted and the front end opening is larger, and is placed at the front end of the rectangular duct 2, the flow place is larger, and an engaging block 5 is arranged on the upper surface of the rectangular duct 2, three engaging blocks 5 are evenly arranged, and two engaging blocks 5 are arranged on the other surface, and the size is arranged along the gap left on the upper surface, so that the assembly can follow the trajectory of the engaging block 5. At the same time, an opening is arranged at the lower end of the engaging block 5, and a movable column is arranged at one end of the opening, and a rotating plate 3 is arranged on the movable column. The movable column controls the rotating plate 3, and the rounded corners of the two ends are set to prevent the phenomenon of squeezing at the opposite end. At the same time, a handle 4 of the same structure is arranged on the rotating plate 3, and the handle 4 is arranged in the recess of the rotating plate 3, which saves space and avoids occupying the position of other devices;
[0023] An embedded end is arranged on the other side surface of the rectangular pipe 2, and a flow device is arranged inside the embedded end, and an inlay plate 13 is arranged on one side. The arrangement of the inlay plate 13 increases the thickness of one end of the flow device, and can be fully engaged on the embedded end. A flow port 6 is arranged on the outer surface of the flow device, and fixed blocks 10 are arranged on both sides of the flow device. At the same time, a connecting block 11 is arranged on the fixed block 10, and the connecting block 11 is connected to the filter plate 8 to ensure that the position of the filter plate 8 is fixed, and a number of activated carbon rods 12 are arranged inside the filter plate 8.
