Detailed Implementation
[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] Example 1:
[0024] Combination Figure 1 and Figure 2 As shown, the outward-opening micro-ventilation window with screen in this embodiment includes a window frame 1. Inside the window frame 1, a main window sash 2 and a ventilation window 3 for micro-ventilation are arranged vertically side by side. A screen 4 is installed on the inner surface of the ventilation window 3. One side of the ventilation window 3 is hinged to one side of the window frame 1 and can be opened to the outside. One side of the screen 4 is hinged to one side of the window frame 1 and can be opened to the inside. When the ventilation window 3 is closed, the connection between the ventilation window 3 and the window frame 1 is provided with a first connection 5, a second connection 6 and a third connection 7 in a stepped manner. Sealing strips 8 are provided at the first connection 5, the second connection 6 and the third connection 7 respectively.
[0025] This invention proposes an outward-opening micro-ventilation window with a screen, which optimizes indoor air quality while maintaining home safety and aesthetics. The window structure mainly includes a window frame 1, made of high-quality aluminum alloy or weather-resistant plastic material to ensure structural stability and a long service life. Inside the window frame 1, a main window sash 2 and a ventilation window 3 specifically designed for micro-ventilation are arranged vertically side-by-side. The main window sash 2 typically uses double or triple-glazed windows to enhance thermal insulation performance, while the ventilation window 3 is made of lightweight and durable materials, easy to operate, and resistant to deformation.
[0026] The interior surface of ventilation window 3 is cleverly equipped with screen window 4. Screen window 4 is made of fine fiber mesh material, which can effectively block pests such as mosquitoes and flies from entering the room, while ensuring good air circulation.
[0027] One side of the ventilation window 3 is hinged to one side of the window frame 1 using precision hardware, allowing the ventilation window 3 to be easily opened to the outside for easy adjustment of airflow. This outward-opening design also effectively prevents rainwater backflow, keeping the indoor environment dry even on rainy days.
[0028] Similarly, one side of the screen window 4 is also hinged to the other side of the window frame 1, but it is designed to open inwards. This allows users to easily clean or replace the screen without opening the ventilation window 3, greatly improving the convenience of use.
[0029] When the ventilation window 3 is closed, to ensure good sealing performance and sound insulation, the connection between the ventilation window 3 and the window frame 1 is provided in a stepped manner with a first connection 5, a second connection 6, and a third connection 7. This not only enhances the stability of the window frame but also ensures that the window frame can be evenly stressed when closed, reducing the possibility of air and water leakage.
[0030] High-quality sealing strips 8 are installed at the first connection 5, the second connection 6, and the third connection 7. These sealing strips 8 are made of materials that are resistant to aging and weathering, and have good elasticity and resilience. They can form a tight seal when the window is closed, effectively isolating external noise, dust, and rainwater, while maintaining a stable indoor temperature and improving living comfort.
[0031] Combination Figure 2 and Figure 3 As shown, the first connection 5 includes a first fixed block 11 and a first movable block 31 disposed on the indoor side of the window frame 1 and the ventilation window 3. The first fixed block 11 and the first movable block 31 cooperate to achieve a tight fit between the window body in the closed state. A first adhesive strip 81 is provided between the first fixed block 11 and the first movable block 31.
[0032] Combination Figure 2 and Figure 3 As shown, the first fixed block 11 is provided with a first mounting groove 111, one side of the first adhesive strip 81 is fixedly installed inside the first mounting groove 111, and the other side of the first adhesive strip 81 is in contact with the first movable block 31.
[0033] Specifically, one side of the first adhesive strip 81 is firmly fixed inside the first mounting groove 111, usually by means of adhesive or mechanical snap-fit, to ensure that it will not fall off or shift during long-term use.
[0034] The first movable block 31 is installed at the corresponding position of the ventilation window 3 to achieve docking. When the ventilation window 3 is closed, the first movable block 31 contacts the other side of the first rubber strip 81, forming a tight seal.
[0035] The contact between the first movable block 31 and the first adhesive strip 81 is not a simple hard contact, but rather utilizes the elasticity of the first adhesive strip 81 to achieve a certain degree of compression deformation, which not only enhances the sealing effect, but also effectively isolates external noise, dust and rainwater, maintaining a comfortable and clean indoor environment.
[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, the second connection 6 includes a second fixed block 12 and a second movable block 32 disposed on the indoor side of the window frame 1 and the ventilation window 3. The second fixed block 12 and the second movable block 32, through their cooperation and the elastic sealing effect of the second adhesive strip 82, ensure excellent sealing performance of the window when closed. A second adhesive strip 82 is disposed between the second fixed block 12 and the second movable block 32.
[0037] Combination Figure 2 and Figure 3 As shown, the second fixing block 12 is symmetrically provided with a second mounting groove 121. The second mounting groove 121 not only facilitates the installation and fixing of the second rubber strip 82, but also disperses the sealing pressure to a certain extent and improves the sealing effect.
[0038] One side of the second adhesive strip 82 is fixedly installed inside the second mounting groove 121, and the other side of the second adhesive strip 82 is in contact with the second movable block 32.
[0039] The second mounting groove 121 ensures that the second adhesive strip 82 can be firmly adhered to or snapped into place. One side of the second adhesive strip 82 is fixedly installed inside the second mounting groove 121, while the other side is in contact with the second movable block 32, forming a tight sealing line. The second movable block 32 ensures that it can form a mating joint when the window is closed, improving the sealing effect and the smoothness of opening and closing the window.
[0040] The contact surface design of the second fixed block 12 and the second movable block 32 ensures that the window can maintain good sealing performance under extreme weather conditions, effectively isolating external noise, dust and rainwater.
[0041] Combination Figure 2 and Figure 3 As shown, the third connection 7 includes a third fixed block 13 and a third movable block 33 disposed on the interior side of the window frame 1 and the ventilation window 3, with a third adhesive strip 83 disposed between the third fixed block 13 and the third movable block 33. The third connection 7 ensures excellent sealing performance of the window when closed. This not only improves the overall performance of the window but also further enhances indoor comfort and safety. The shape and size of the third fixed block 13 have been calculated to ensure perfect alignment with the third movable block 33. The shape and depth of the third mounting groove 131 have been planned to accommodate and fix the third adhesive strip 83.
[0042] Combination Figure 2 and Figure 3 As shown, the third fixed block 13 is provided with a third mounting groove 131, one side of the third adhesive strip 83 is fixedly installed inside the third mounting groove 131, and the other side of the third adhesive strip 83 is in contact with the third movable block 33.
[0043] One side of the third adhesive strip 83 is fixedly installed inside the third mounting groove 131, usually by adhesive or mechanical snap-fit, to ensure that it will not fall off or shift during long-term use. The third connection 7, through the cooperation of the third fixing block 13, the third moving block 33 and the third adhesive strip 83, achieves a tight fit and good seal of the window in the closed state, providing a solid guarantee for the outward-opening micro-ventilation window with screen.
[0044] Combination Figure 2 and Figure 3 As shown, the first adhesive strip 81 and the third adhesive strip 83 are EPDM rubber strips, and the second adhesive strip 82 is a duckbill strip.
[0045] In the design of outward-opening micro-ventilation windows with screens, the selection of the sealing strip 8 is crucial to ensuring the window's sealing performance and durability. The first sealing strip 81 and the third sealing strip 83 are made of EPDM rubber, while the second sealing strip 82 is a duckbill strip. This not only reflects a deep understanding of the characteristics of different sealing parts but also demonstrates a precise grasp of material properties.
[0046] Ethylene propylene diene monomer (EPDM) rubber strips, used as the material for the first rubber strip 81 and the third rubber strip 83, possess several excellent performance characteristics. Firstly, EPDM rubber strips exhibit excellent weather resistance and aging resistance, maintaining a stable sealing effect under extreme weather conditions and effectively isolating external noise, dust, and rainwater. EPDM rubber strips also possess good elasticity and resilience, forming a tight seal line when the window is closed, ensuring a secure seal.
[0047] In the first connection 5 and the third connection 7, EPDM adhesive strips are cleverly fixedly installed inside the first mounting groove 111 and the third mounting groove 131, forming a tight contact with the first movable block 31 and the third movable block 33. This not only improves the sealing performance but also ensures the smoothness and stability of the window during opening and closing.
[0048] The second sealing strip 82 is a duckbill strip, taking into full account the special requirements of the second connection 6. The duckbill strip, with its unique shape and material properties, exhibits excellent sealing performance. Its special lip design allows it to fit tightly against the second movable block 32, forming an effective sealing line that effectively prevents the intrusion of external noise, dust, and rainwater. At the same time, the duckbill strip also has good elasticity and wear resistance, maintaining stable sealing performance during long-term use.
[0049] In the second connection 6, the duckbill strip is fixedly installed inside the second mounting groove 121, forming a tight contact with the second movable block 32. This not only improves the sealing performance but also enhances the stability and durability of the window in the closed state.
[0050] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
