Description

Technical Field

[0001] This utility model relates to a door and window filtration and ventilation structure. Background Technology

[0002] In the residential building sector, indoor air circulation is a crucial factor. Generally, if a cleanliness level is required, a cleanroom air conditioning system or a simple supply and exhaust system will be installed. This system will be equipped with one or more stages of air filtration devices to achieve the required air cleanliness, depending on the usage requirements.

[0003] However, in some situations, due to space constraints or other reasons, no ventilation system is installed, but there are requirements for the dust content in the environment, such as in high-rise buildings. Although ventilation can be achieved by opening windows, the height of high-rise buildings results in high wind noise, affecting human comfort. Therefore, many doors and windows are equipped with filtration and ventilation structures. However, the existing filtration and ventilation structures, once installed, will affect the structural stability of the doors and windows, and are prone to deformation, affecting the sealing performance, and the filtration effect is poor. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a door and window filtering and ventilation structure.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A door and window filtration and ventilation structure includes an outer frame and a filtration and ventilation crossbeam fixedly installed inside the upper part of the outer frame. The filtration and ventilation crossbeam includes a frame body, a cover plate located on the inner side of the frame body and hinged to the frame body via a pivot, and strip-shaped air holes opened on the outer side of the frame body. The frame body has an insert groove that connects to the strip-shaped air holes, a filter strip filled in the insert groove, and an aluminum alloy mesh plate fixed to the frame body by screws for fixing the filter plate.

[0007] Preferably, there are two insert slots, which are arranged in a strip shape.

[0008] Preferably, the filter strip is an activated carbon filter cotton strip.

[0009] Preferably, the opening of the frame assembly cover plate is also fitted with a sealing ring by adhesive.

[0010] Preferably, a long support frame strip, which is fixedly installed to the outer frame 1, is welded to the lower middle part of the filter ventilation crossbar, and a short support frame strip, which is fixedly installed to the outer frame, is welded to the upper middle part of the filter ventilation crossbar.

[0011] Preferably, telescopic support rods are provided at both ends of the cover plate facing the frame. The base of the telescopic support rod is hinged to the lower end of the side of the frame, and the output end of the telescopic support rod is hinged to the upper end of the inner side of the cover plate.

[0012] The beneficial effects of this utility model are as follows: the structure purifies the air through activated carbon filter strips while enhancing ventilation through the structure of strip-shaped air holes and cover plates. The filter strips can be replaced when they age or their effectiveness decreases, making maintenance simple and extending their service life. The design of the support frame strips and telescopic support rods enhances the overall structural stability, making the doors and windows less prone to loosening or deformation during long-term use. The use of sealing rings ensures the airtightness of the cover plate after it is closed, further improving the filtration effect and indoor air quality. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0018] Example

[0019] like Figure 1-4 As shown, a door and window filtration and ventilation structure includes an outer frame 1 and a filtration and ventilation crossbar 2 fixedly installed inside the upper part of the outer frame 1.

[0020] The filter ventilation frame 2 includes a frame body 21, a cover plate 22 located on the inner side of the frame body 21 and hinged to the frame body 21 via a pivot, and strip-shaped air holes 23 opened on the outer side of the frame body 21. The frame body 21 has an insert groove 211 that communicates with the strip-shaped air holes 23, a filter strip 212 filled in the insert groove 211, and an aluminum alloy mesh plate 213 fixed to the frame body 21 by screws for fixing the filter plate 212.

[0021] There are two mounting slots 211, which are arranged in a strip shape. Specifically, the strip-shaped air holes 23 corresponding to the mounting slots 211 can improve the ventilation volume.

[0022] Filter strip 212 is an activated carbon filter strip that can filter and purify the air.

[0023] It should be further explained that after the filter strip 212 ages and its filtration and purification effect decreases, it can be replaced by disassembling the aluminum alloy mesh plate 213.

[0024] The opening of the cover plate 22 on the frame 21 is also fitted with a sealing ring 214 by adhesive. Specifically, when the cover plate 22 is closed, the sealing ring 214 prevents outside air from flowing in.

[0025] A long support frame 24, which is fixedly installed to the outer frame 1, is welded to the lower center of the filter ventilation crossbeam 2, and a short support frame 25, which is fixedly installed to the outer frame 1, is welded to the upper center of the filter ventilation crossbeam 2. Specifically, the long support frame 24 and the short support frame 25 improve the assembly stability between the filter ventilation crossbeam 2 and the outer frame 1.

[0026] Telescopic support rods 221 are provided at both ends of the side of the cover plate 22 facing the frame 21. The base of the telescopic support rod 221 is hinged to the lower end of the side of the frame 21, and the output end of the telescopic support rod 221 is hinged to the upper end of the inner side of the cover plate 22. The telescopic support rod 221 can provide stable support after the cover plate 22 is opened.

[0027] In practical application, the cover plate 22 facing the room can be opened directly through the telescopic support rod 221. At this time, the air outside enters through the strip-shaped air hole 23, is filtered by the filter strip 212 and then enters the room, completing the filtration and ventilation.

[0028] It should be further explained that, since filter strip 212 is an activated carbon filter strip, it can not only filter and purify the air, but also absorb sound.

[0029] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
