Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction, and in particular to a window air pressure balancing device. Background Technology
[0002] After the fixed window is installed, with the inner and outer rubber strips on all four sides of the glass sealed, the glass and the surrounding window frame profile form a closed cavity. Under the action of outdoor wind pressure, the inner rubber strips will be compressed, and gaps will form between the outer rubber strip and the glass. In rainy weather, rainwater will enter the internal cavity of the profile through the gaps. In order to facilitate the smooth drainage of rainwater, vents need to be set at the top and drainage holes at the bottom. In this way, the pressure inside the cavity around the glass is the same as the pressure outside the window, so that rainwater can be drained smoothly.
[0003] Ventilation holes are usually created by cutting off a section of the outer sealant strip from the top of the window frame. In extreme weather, rainwater can seep through this hole, over the edge of the glass, and eventually enter the room through the glass pressure line, causing indoor water leakage.
[0004] To address the above problems, a window air pressure balancing device is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a window air pressure balancing device, which aims to improve the existing technology where the ventilation hole is generally achieved by cutting off a section of the outer rubber strip of the glass at the top of the window frame. In extreme weather, rainwater can flow through this hole, over the edge of the glass, and eventually enter the room through the glass pressure line, causing indoor water leakage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a window pressure balancing device, comprising a window frame, glass installed inside the window frame, a pressure balancing device provided on the outside of the window frame, two buckles fixedly connected to one side of the pressure balancing device, a glass surface provided on the other side of the pressure balancing device, a grille fixedly connected to the bottom of the pressure balancing device, multiple ventilation holes one at the bottom of the pressure balancing device, a second ventilation hole two on the upper side inside the pressure balancing device, a ventilation chamber provided inside the pressure balancing device, and a water-blocking wall provided at the top of the pressure balancing device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 - Figure 5 An embodiment of this utility model provides a window air pressure balancing device, including a window frame 5, a glass 3 installed inside the window frame 5, an air pressure balancing device 1 set on the outside of the window frame 5, two buckles 11 fixedly connected to one side of the air pressure balancing device 1, a glass surface 17 set on the other side of the air pressure balancing device 1, a grille 13 fixedly connected to the bottom of the air pressure balancing device 1, multiple ventilation holes 12 opened at the bottom of the air pressure balancing device 1, a second ventilation hole 14 opened on the upper side inside the air pressure balancing device 1, a ventilation chamber 16 set inside the air pressure balancing device 1, and a water-blocking wall 15 set on the top of the air pressure balancing device 1.
[0033] Specifically, the window frame 5 is used to install the glass 3, providing a supporting frame for the entire window's air pressure balancing device. The glass 3 is installed inside the window frame 5 to block the indoor and outdoor spaces. The air pressure balancing device 1 is used to balance the air pressure inside the profile cavity of the window frame 5 with the outdoor air pressure, ensuring smooth drainage while preventing rainwater from entering the room. The buckle 11 is used to securely fasten the air pressure balancing device 1 to the window frame 5. The glass surface 17 is used to contact the glass 3, forming a ventilation cavity 16. The grille 13 is used to block most of the rainwater and some flying insects, lint, and other foreign objects. Inside the profile cavity of the window frame 5, multiple vent holes 12 are opened at the bottom of the air pressure balancing device 1 to allow outdoor air to enter the vent cavity 16 under air pressure. Vent holes 14 are opened on the upper side inside the air pressure balancing device 1 to guide the air in the vent cavity 16 into the profile cavity of the window frame 5. The vent cavity 16 is used to receive the air entering from the vent holes 12 and guide it to the vent holes 14. The water-blocking wall 15 is used to block a small amount of rainwater entering the vent cavity 16 and prevent it from entering the profile cavity of the window frame 5.
[0034] Reference Figure 1 - Figure 5 The window frame 5 has two drainage devices 2 at the bottom. The window frame 5 has profile wing wall 4 inside. The window frame 5 has glass pressure line 6 on the outside. The window frame 5 has inner glass sealing strip 7 on the outside. The inner glass sealing strip 7 is located on the outside of the profile wing wall 4. The air pressure balancing device 1 is located on the outside of the glass 3. The window frame 5 has outer glass sealing strip 8 on the outside. The outer glass sealing strip 8 is located on the outside of the glass 3.
[0035] Specifically, the window frame 5 serves as the basic structure of the entire device, used to support and fix other components. The drainage device 2 is used to promptly drain water that enters the profile cavity of the window frame 5, preventing water from damaging the structure and function of the window frame 5. The profile wing wall 4 is used to build a stable internal structure and also assists in fixing other components, enhancing the stability of the entire window frame 5. The glass pressure line 6 is used to firmly fix the position of the glass 3, preventing the glass from shaking or shifting within the window frame 5. The inner glass sealing strip 7 enhances the sealing performance between the window frame 5 and the glass 3, effectively preventing dust, moisture, etc., from entering the room from the inside. The pressure balancing device 1 is located on the outside of the glass 3, used to balance the air pressure between the internal profile cavity of the window frame 5 and the outside, ensuring smooth drainage and preventing rainwater from entering the room through the vents in extreme weather, thus improving the window's waterproof performance. The outer glass sealing strip 8 enhances the sealing performance between the window frame 5 and the glass 3 on the outside, further improving the overall sealing and waterproof performance of the window.
[0036] Working principle: During operation, outdoor air, under air pressure, enters the ventilation chamber 16 through the vent 12 at the bottom of the air pressure balancing device 1, and then enters the profile cavity of the window frame 5 through the second vent 14. This ensures air pressure balance within the cavity of the window frame 5 under wind pressure, guaranteeing smooth drainage. The grille 13 on the device can block most rainwater, and the small amount of rainwater entering the ventilation chamber 16 is blocked by the water-blocking wall 15. Only air can enter the profile cavity, preventing indoor water seepage during extreme wind and rain. At the same time, the grille 13 can also prevent some flying insects, lint, and other foreign objects from entering the cavity, keeping the area around the glass 3 clean. The drainage device 2 at the bottom of the window frame 5 is responsible for draining the rainwater that enters the profile cavity of the window frame 5.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
