[0002] As people's demands for the quality of their living environment increase, indoor air quality has become a growing concern. While traditional window ventilation can introduce fresh air, it faces numerous challenges in certain situations, such as noise pollution, cold winters, hot summers, dust intrusion, and safety hazards (such as the risks associated with opening windows in high-rise residential buildings). To address these challenges, fresh air systems have emerged and become an indispensable ventilation device in modern buildings.

[0003] However, some existing fresh air products still have certain shortcomings in their design. For example, because the exhaust vents are easily clogged by dust, long-term use can lead to a decline in air quality and a reduction in airflow efficiency. Therefore, regular cleaning is necessary, but most current products have multiple small exhaust vents, resulting in difficulties and low cleaning efficiency. Utility Model Content

[0024] Reference Figures 1 to 5 A window frame with a cover plate 7 includes a frame body 1, which is a single-frame, double-frame, or multi-frame shape. The frame body 1 can be integrally formed or spliced ​​together. The frame body 1 has a receiving cavity 2 inside, which can be one or more. The receiving cavity 2 can be located on the frame edge and / or the inner edge of the frame body 1. Preferably, the receiving cavity 2 is located on the inner edge of the frame body 1.

[0025] The fresh air system module 3 is installed within the receiving cavity 2. Preferably, the fresh air system module 3 is detachably installed within the receiving cavity 2, and can be installed by means of snap-fit, fitting, or screws. The fresh air system module 3 can also be considered an air purifier, used to purify outdoor air before releasing it into the room. Preferably, the fresh air system module 3 has a negative ion purification function.

[0026] At least one air inlet 4 is provided on one side of the receiving cavity 2, allowing air to enter the receiving cavity 2 through the air inlet 4. An opening 5 is provided on the other side of the receiving cavity 2, facing away from the air inlet 4, or in other words, facing towards the interior. At least one slot 6 is provided along the edge of the opening 5, extending from the interior of the receiving cavity 2 to the exterior of the frame 1. A cover plate 7 is detachably attached to the opening 5, and the slot 6 and the cover plate 7 together form an exhaust vent. The cover plate 7 is detachably connected to the frame 1 by means of snap-fit, screw locking, magnetic attraction, etc. This detachable connection of the cover plate 7 facilitates the installation and routine maintenance of the fresh air system module 3.

[0027] After the cover plate 7 is removed from the frame 1, the slot 6 is exposed when viewed from the inside to the outside. With this design, if it is necessary to clean the vent, simply remove the cover plate 7, and the slot 6 will be exposed. The user can directly use a cloth or brush to clean the slot 6, which not only makes cleaning more thorough but also improves cleaning efficiency and greatly reduces the difficulty of cleaning.

[0028] In some embodiments, the cover plate 7 and the frame 1 are connected by a snap-fit ​​structure. Specifically, the cover plate 7 is provided with a snap-fit ​​part 8, and the frame 1 is provided with a snap-fit ​​part 9 that mates with the snap-fit ​​part 8. The cover plate 7 and the frame 1 are snap-fitted together. At least one of the snap-fit ​​part 8 and the snap-fit ​​part 9 is elastically deformable. The cover plate 7 may also have a snap-fit ​​part 8 on only one side, with the other side connected by a limiting structure. The snap-fit ​​structure facilitates the assembly and disassembly of the cover plate 7 and eliminates the need for fasteners, reducing the number of parts.

[0029] In some embodiments, the edge of the opening 5 is provided with an outwardly extending flange 10, and the slot 6 is provided on the side of the flange 10 that contacts the cover plate 7. The outwardly extending flange 10 increases the structural strength around the opening 5, making it more resistant to external pressure or impact, avoiding damage caused by accidental collisions, and improving overall durability and reliability. Moreover, the design of the flange 10 can increase the contact area between the edge of the opening 5 and the cover plate 7, thereby improving the sealing performance.

[0030] In some embodiments, an exhaust port 11 is provided within the slot 6, intersecting the extending direction of the slot 6 and penetrating the flange 10. Preferably, the penetrating direction of the exhaust port 11 is perpendicular to the extending direction of the slot 6. This design increases the air exhaust path and improves ventilation efficiency.

[0031] In some embodiments, the receiving cavity 2 is provided with at least a separated air inlet layer 12 and an air outlet layer 13, and a partition layer disposed between the air inlet layer 12 and the air outlet layer 13. The partition layer is provided with a through channel 14, the air inlet layer 12 is provided with an air inlet 4 communicating with the outside, and the opening 5 is disposed in the air outlet layer 13. The fresh air system module 3 is installed in the channel 14 of the partition layer. It is understood that the fresh air system module 3 and the partition layer separate the air inlet layer 12 and the air outlet layer 13, and the air in the air inlet layer 12 needs to be purified by the fresh air system module 3 before entering the air outlet layer 13.

[0032] In some embodiments, the air intake layer 12 has an open end facing the outside, and the open end is detachably connected to the rear cover 15. Specifically, the open end is detachably connected to the rear cover 15 via a snap-fit ​​structure, and the rear cover 15 is provided with the air intake 4. When maintenance is required, the rear cover 15 can be removed for maintenance.

[0033] In some embodiments, the rear cover 15 has an inner locking arm 16 and an outer locking arm 17 extending toward the air intake layer 12 on at least one side. A waterproof space 19 is provided between the inner locking arm 16 and the outer locking arm 17, and both the inner locking arm 16 and the outer locking arm 17 are provided with through air inlets 4. The number of air inlets 4 is at least one, and preferably, the air inlets 4 of the inner locking arm 16 and the outer locking arm 17 are arranged opposite to each other. With this design, water entering from the air inlet 4 of the outer locking arm 17 will flow away through the waterproof space 19, and outdoor rainwater is less likely to enter the receiving cavity 2.

[0034] In some embodiments, the sidewall of the air intake layer 12 is provided with a latching protrusion 18 extending into the receiving cavity 2. In the direction from the air intake layer 12 to the air outlet layer 13, the latching protrusion 18 engages between the inner latching arm 16 and the outer latching arm 17. This design results in a tighter connection between the rear cover 15 and the frame 1, and better sealing.

[0035] In some embodiments, the rear cover 15 does not protrude from the frame 1. Preferably, the side of the rear cover 15 facing the outside is flush with the side of the frame 1 facing the outside. This prevents rainwater from entering the interior of the frame 1.

[0036] In some embodiments, the frame 1 partition layer includes a heat insulation layer 20 and a barrier layer 21. The heat insulation layer 20 is made of heat insulation material, and the barrier layer 21 is disposed adjacent to the heat insulation layer 20. At least one barrier layer 21 is present. The barrier layer 21 is used to block sound, improving the sound insulation performance of this embodiment. The heat insulation layer 20 is made of heat insulation material, which is a material with high strength and low thermal conductivity, such as PC, PEEK, PSU, PA, etc. The barrier layer 21 is disposed adjacent to the heat insulation layer 20, and at least one barrier layer 21 is present. Specifically, the barrier layer 21 can be disposed between the heat insulation layer 20 and the air inlet layer 12 / air outlet layer 13. This design gives this embodiment good sound insulation and heat insulation performance.

[0037] In some embodiments, the barrier layer 21 and / or the thermal insulation layer 20 are filled with a filler. The filler may be a polyurethane foam, polystyrene foam, phenolic foam, or other fillers with good thermal and sound insulation properties. This further improves the sound and thermal insulation performance of this embodiment.

[0038] Reference Figures 1 to 5This utility model also discloses a fresh air system door and window, including the window frame with cover plate 7 mentioned above, and a fresh air system module 3 disposed in the receiving cavity 2. The fresh air system module 3 has an air inlet end 32 and an air outlet end 33. The air inlet end 32 is connected to the air inlet 4, and the air outlet end 33 is connected to the exhaust port 11. Air enters the interior of the receiving cavity 2 from the air inlet 4, and then enters the interior of the fresh air system module 3 from the air inlet end 32. After purification, the air is discharged from the air outlet end 33 and enters the room from the exhaust port 11.

[0039] In some embodiments, the fresh air system doors and windows are also equipped with a control panel 34, which can be mechanical or touch-sensitive. Preferably, the control panel 34 is also equipped with a display screen. The control panel 34 can be installed in the window frame or outside the window frame, for example, by leading a wire to install the control panel 34 on the wall.

[0040] The above embodiments do not limit the scope of protection of this invention. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this invention are still within the scope of this invention.
