Embodiment 1

[0036] Such as figure 1 As shown, a small hole type ventilation and noise reduction door window frame includes a first surface layer 1, a second surface layer 2 matched with the first surface layer 1, the first surface layer 1 and the second surface layer 2 cooperate with each other, Form the frame.

[0037] An intermediate layer 3 is arranged between the first surface layer 1 and the second surface layer 2, a first cavity is formed between the first surface layer 1 and the intermediate layer 3, and a second cavity is formed between the second surface layer 2 and the intermediate layer 3. In the cavity, the plane where the middle layer 3 is located is parallel to the plane where the first surface layer 1 is located and the plane where the second surface layer 2 is located. Several first ventilation holes 4 are provided on the first surface layer 1 , several second ventilation holes 5 are provided on the second surface layer 2 , and several third ventilation holes 6 are provid...

Embodiment 2

[0044] A small-hole type ventilation and noise reduction door and window frame, including a first surface layer 1, a second surface layer 2 matched with the first surface layer 1, the first surface layer 1 and the second surface layer 2 cooperate with each other to form a frame body .

[0045] Two intermediate layers 3 are arranged between the first surface layer 1 and the second surface layer 2, and a cavity is formed between the intermediate layers 3, between the first surface layer 1 and the intermediate layer 3 close to the first surface layer 1 The first cavity is formed, and the second cavity is formed between the second surface layer 2 and the intermediate layer 3 close to the second surface layer 2. The plane of the intermediate layer 3 is respectively the same as the plane of the first surface layer 1 and the second surface layer 2. The planes are parallel. Several first ventilation holes 4 are provided on the first surface layer 1 , several second ventilation holes ...

Abstract

The invention discloses a small-hole type door and window frame with the effects of ventilation and noise elimination, which aims to solve the problems that the existing door and window does not simultaneously have the effects of ventilation and noise elimination, and a bi-directional composite sound insulation window curtain is complex in manufacturing process and relatively high in production cost. The small-hole type door and window frame with the effects of ventilation and noise elimination comprises a first surface layer and a second surface layer, wherein the first surface layer and the second surface layer are matched to form a frame body, a middle layer is arranged between the first surface layer and the second surface layer, a first cavity is formed between the first surface layer and the middle layer, a second cavity is arranged between the second surface layer and the middle layer, a plurality of first ventilation holes are formed in the first surface layer, a plurality of second ventilation holes are formed in the second surface layer, and a plurality of third ventilation holes are formed in the middle layer. The small-hole type door and window frame has the beneficial effects that the conception is ingenious, the prepared product simultaneously has the effects of ventilation and noise elimination through improving the existing door and window frame, the use is convenient, the adaptability is good, and the small-hole type door and window frame can be used in the same way as the existing door and window frame.

Description

technical field [0001] The invention relates to the field of daily life, in particular to a small-hole ventilation and noise-reduction door and window frame, which has the functions of noise reduction and ventilation. Background technique [0002] With the rapid development of my country's economy, people's economic frequency has greatly increased. At the same time, with the "two-speed" advancement of urbanization and industrialization in our country, more and more people live in downtown areas, and noise pollution has a greater impact on people's lives. The air pollution caused by interior decoration, the turbidity of indoor air caused by the lack of air circulation are more and more harmful to people's health, and have a serious impact on people's daily life, work and study. [0003] At this point, existing windows and doors begin to show their limitations. When the doors and windows are opened to ventilate and discharge indoor turbid or polluted air, traffic noise pollu...
