Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a micro-ventilation window. Background Technology

[0002] On the exterior walls of residential buildings or high-rise buildings, micro-ventilation windows are sometimes installed next to windows to satisfy both the requirement for a wide view and the requirement for air exchange between indoors and outdoors.

[0003] A micro-ventilation window, also known as a breathing window or slit ventilation window, mainly includes a frame, an exterior side panel and an interior side panel rotatably mounted on the frame, and a ventilation assembly and a screen fixed to the frame. The ventilation assembly and screen are arranged side-by-side along the indoor-outdoor direction and are positioned between the exterior and interior side panels, as disclosed in Japanese Patent Document No. JP2018159209A, which describes a door and window equipped with a ventilation device. When the exterior side panel of the micro-ventilation window opens to the outside and the interior side panel opens to the inside, a longitudinal ventilation slit is formed on one side of the micro-ventilation window. This slit absorbs wind from the building's exterior wall, allowing for indoor and outdoor air circulation through the ventilation assembly and screen, thus achieving effective natural ventilation of the interior. Simultaneously, the screen also serves to prevent insects.

[0004] In existing micro-ventilation windows, the frame is made of ordinary aluminum profiles, with an integral mounting arm extending from the inner wall at the midpoint between the indoor and outdoor directions. The ventilation components and screens are fixed to the mounting arm, achieving a fixed installation on the frame. However, micro-ventilation windows made of ordinary aluminum profiles have low thermal insulation performance. To improve the thermal insulation performance of micro-ventilation windows, the ordinary aluminum profiles constituting the frame need to be replaced with thermally broken aluminum profiles to form a thermally insulated structure that makes it difficult to transfer heat to the indoor side. However, thermally broken aluminum profiles include an interlocking thermal break bridge (i.e., a thermal insulation strip) and the aluminum profile itself, meaning the frame shape is limited. This makes it difficult to implement the original fixed installation structure of the ventilation components and screens on thermally broken aluminum profiles, making it difficult to fix the ventilation components and screens inside the thermally broken aluminum profile. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a micro ventilation window that can improve heat insulation performance and achieve fixed installation of ventilation components and screens.

[0006] To achieve the above objectives, this utility model provides a micro ventilation window, including a window frame, a ventilation component and a screen installed within the window frame, wherein the ventilation component and the screen are arranged side by side along the indoor and outdoor direction, and the micro ventilation window also includes fixing accessories;

[0007] The window frame includes a pair of vertical frame profiles and a pair of horizontal frame profiles fixed between the pair of vertical frame profiles. Both the pair of vertical frame profiles and the pair of horizontal frame profiles are thermally broken aluminum profiles. The thermally broken aluminum profiles include an outdoor side profile and an indoor side profile arranged side by side along the indoor-outdoor direction, and a thermally broken bridge fixed between the outdoor side profile and the indoor side profile.

[0008] The fixing fitting is a separate structure from the window frame and is fixed to the outdoor or indoor side profile of the vertical frame profile. The fixing fitting includes a first fixing part distributed on the outer periphery of the ventilation component and a second fixing part distributed on the outer periphery of the screen. The ventilation component is fixed to the first fixing part and the screen is fixed to the second fixing part.

[0009] In the micro-ventilation window involved in this application, both the vertical and horizontal frame profiles constituting the window frame are made of thermally broken aluminum profiles, which can effectively block the heat transfer between the indoor and outdoor areas, improve the overall thermal insulation performance of the micro-ventilation window, effectively reduce the overall heat loss of the micro-ventilation window, and contribute to the promotion of energy conservation and environmental policies. At the same time, by configuring fixing accessories independent of the window frame, the ventilation components and screens are fixed to the vertical frame profiles through fixing accessories. In particular, based on the split structure between the fixing accessories and the window frame, this application can avoid interference with the assembly of the thermally broken aluminum profiles constituting the window frame, and can also realize the fixed installation of the ventilation components and screens, ultimately making it easy to fix the ventilation components and screens within the thermally broken aluminum profiles.

[0010] Furthermore, the fixing accessory is fixed to the outdoor side profile of the vertical frame profile. Preferably, the fixing structure consists of a profile fixing part integrally extending from the outdoor side profile of the vertical frame profile. The ventilation component, the first fixing part, and the profile fixing part are stacked sequentially along the outdoor-to-indoor direction, and the three are fixed together by at least one locking screw. When there are multiple locking screws, they are arranged sequentially from top to bottom. In this way, the locking screws secure the ventilation component, the fixing accessory, and the vertical frame profile, making the fixing structure of the ventilation component, the fixing accessory, and the vertical frame profile simple and easy to implement.

[0011] Furthermore, the first fixing part is a flat plate structure. The profile fixing part includes a first flat plate portion, a bent portion, and a second flat plate portion connected sequentially along the direction away from the outdoor profile. A portion of the first flat plate portion abuts against the indoor side of the ventilation component. A fitting groove is formed between the bent portion and the second flat plate portion, and the first fixing part is fitted into the fitting groove. In this way, the first flat plate portion of the outdoor profile of the vertical frame and the first fixing part of the fixing accessory both abut against the indoor side of the ventilation component and are in surface contact with the ventilation component, improving the installability of the ventilation component and facilitating its fixed installation. At the same time, the profile fixing part forms a fitting groove through bending, which plays a certain positioning role when the first fixing part is fixed. Furthermore, after the ventilation component is fixed, the first fixing part fits between the ventilation component and the second flat plate portion, further improving the installability of the fixing accessory.

[0012] Furthermore, the preferred fixing structure between the fixing accessory and the screen is that the second fixing part has a fixing groove with an opening facing the screen, and the screen includes a screen body and a pair of screen frames fixed to both sides of the screen body along the width direction of the screen body. The screen frames can elastically deform and engage in the fixing groove of the second fixing part. Thus, when fixing the screen, it is only necessary to press the screen frame into the fixing groove of the second fixing part, and then the screen frame's rebound achieves engagement (i.e., tight fit) in the fixing groove, improving the screen's installability and facilitating its installation.

[0013] Preferably, the screen frame is an injection molded part, which facilitates the production and manufacturing of the screen frame.

[0014] Preferably, the fixing accessory has a first limiting protrusion fixed to the wall of the fixing groove, and the outer circumferential surface of the screen frame has a second limiting protrusion. The first limiting protrusion abuts against one side of the second limiting protrusion along the direction in which the screen frame disengages from the fixing groove. Thus, after the screen is fixed, the abutting cooperation between the first and second limiting protrusions restricts the second limiting protrusion from disengaging from the fixing groove, thereby restricting the screen frame from disengaging from the fixing groove of the fixing accessory, improving the fixing reliability between the screen frame and the fixing accessory.

[0015] Furthermore, the fixing accessories are provided in pairs, and the pair of fixing accessories are provided on both sides of the screen window along the width direction of the screen window, so that the screen window and the ventilation component are reliably fixed in the window frame, thereby improving the overall structural strength of the micro ventilation window.

[0016] Furthermore, the micro-ventilation window also includes an outdoor side panel that can be opened and closed and installed on the outdoor side of the window frame, and an indoor side panel that can be opened and closed and installed on the indoor side of the window frame. The ventilation component is located on the outdoor side of the screen and on the indoor side of the outdoor side panel, and the screen is located on the outdoor side of the indoor side panel. When both the outdoor side panel and the indoor side panel are closed, the ventilation component and the screen are covered between the outdoor side panel and the indoor side panel. When the outdoor side panel is open, the ventilation component is exposed on the outdoor side of the micro-ventilation window. When the indoor side panel is open, the screen is exposed on the indoor side of the micro-ventilation window. With both exterior and interior side panels that can be opened and closed, the micro-ventilation window can be easily opened or closed. When the micro-ventilation window is open, the ventilation components and screens allow for air circulation between the indoor and outdoor areas, providing effective natural ventilation to the room. The screens also serve to prevent insects. When the micro-ventilation window is closed, the ventilation components and screens are concealed within the window frame by the exterior and interior side panels. This not only improves the appearance of the micro-ventilation window but also protects the ventilation components and screens from contamination in this state.

[0017] Preferably, the cross-sectional shape of the fixing accessory is approximately I-shaped. Based on this, the first fixing part and the second fixing part are arranged side by side along the width direction of the screen window. The second fixing part has an abutting part that abuts against the indoor side of the ventilation component. The first fixing part and the abutting part are flush, which makes it easier to fix the ventilation component.

[0018] Furthermore, the ventilation component in this application is also waterproof. A preferred structure of the ventilation component is as follows: the ventilation component includes several horizontally arranged and fixedly connected louvers, with a ventilation channel connecting the indoor and outdoor areas formed between adjacent louvers. The ventilation channel has an air inlet section with an opening facing the outdoor side. Each louver includes a horizontal main profile and a vertical profile integrally extended from the surface of the horizontal main profile. The vertical profile is located within the ventilation channel, and the indoor side of the air inlet section is blocked by the horizontal main profile. The horizontal main profile and the vertical profile cause the ventilation channel to meander. Thus, while achieving ventilation, the ventilation component can effectively suppress the intrusion of rainwater from the outdoor side into the indoor area, ensuring the water tightness of the micro-ventilation window. Therefore, the micro-ventilation window has good heat insulation performance, ventilation function, insect-proof function, and waterproof function, effectively enhancing the product competitiveness of the micro-ventilation window.

[0019] Preferably, the fixing accessory is an aluminum profile and is a one-piece molded part, which facilitates the production and manufacturing of the fixing accessory, and also gives the fixing accessory itself good structural strength, thereby improving the fixing reliability of the ventilation component and the screen.

[0020] Furthermore, in the thermally broken aluminum profile, the outdoor profile and the thermal break bridge, as well as the indoor profile and the thermal break bridge, are all fixed by riveting, which is simple to implement and reliable.

[0021] As described above, the micro-ventilation window of this utility model has the following beneficial effects:

[0022] 1. The window frame of the micro-ventilation window is made of thermally broken aluminum profile, which can effectively block the heat transfer between the indoor and outdoor areas and improve the overall heat insulation performance of the micro-ventilation window; 2. The ventilation components and screens are fixed to the vertical frame profiles by fixing accessories. Based on the split structure between the fixing accessories and the window frame, it can avoid interference with the assembly of the thermally broken aluminum profiles that make up the window frame, and can also realize the fixed installation of the ventilation components and screens, making it easy to fix the ventilation components and screens within the thermally broken aluminum profiles.

[0073] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0074] This application provides a micro-ventilation window 10. For ease of description, in the following embodiments, the directions are defined as follows: the indoor-outdoor direction is defined as the front-back direction, with the outdoor direction being the front direction and the indoor direction being the rear direction; the horizontal direction orthogonal to the indoor-outdoor direction is defined as the left-right direction; and the vertical direction orthogonal to the indoor-outdoor direction is defined as the up-down direction. Therefore, the front-back direction is also the thickness direction of the micro-ventilation window 10, the left-right direction is also the width direction of the micro-ventilation window 10, and the up-down direction is also the height direction of the micro-ventilation window 10. Based on this, Figure 3 and Figure 6 In the view shown, the top and bottom sides of the paper are the front and back directions, respectively; the left and right sides of the paper are the left and right directions, respectively; and the front and back sides of the paper are the top and bottom directions, respectively.

[0075] like Figure 1 and Figure 2 ,or Figure 4 and Figure 5 As shown, the micro-ventilation window 10 involved in this application is a narrow window, that is, the width of the micro-ventilation window 10 in the left-right direction is much smaller than its height in the up-down direction. For example... Figures 4 to 7 As shown, the micro-ventilation window 10 includes a window frame 30, a ventilation component 40, a screen 50, and fixing accessories 60. The ventilation component 40 and the screen 50 are both installed inside the window frame 30, and are arranged side-by-side along the indoor / outdoor direction. When the micro-ventilation window 10 is open, as shown... Figure 4 and Figure 5 As shown, the outdoor area and the indoor area are connected by the ventilation component 40 and the screen window 50. Outdoor air will flow to the indoor area, effectively ventilating the room naturally and giving the micro ventilation window 10 a micro ventilation function. At the same time, the screen window 50 also serves to prevent insects.

[0076] Furthermore, such as Figures 4 to 6As shown, the window frame 30 is a narrow window frame. The window frame 30 includes a pair of vertical frame profiles 31 that extend vertically and side by side, and a pair of horizontal frame profiles 32 that extend side by side and side by vertically. The pair of horizontal frame profiles 32 are fixed between the pair of vertical frame profiles 31. Both the pair of vertical frame profiles 31 and the pair of horizontal frame profiles 32 are thermally broken aluminum profiles 33. The thermally broken aluminum profile 33 includes an outdoor side profile 331 and an indoor side profile 332 that are side by side along the indoor-outdoor direction, and a thermally broken bridge 333 fixed between the outdoor side profile 331 and the indoor side profile 332. That is, both the two vertical frame profiles 31 and the two horizontal frame profiles 32 constituting the window frame 30 include an outdoor side profile 331, a thermally broken bridge 333, and an indoor side profile 332 that are fixedly connected from front to back. The thermal break bridge 333 is made of thermal insulation material, such as PA66 thermal insulation material; the outdoor profile 331 and the indoor profile 332 are both aluminum profiles. In the micro-ventilation window 10, the two vertical frame profiles 31 and the two horizontal frame profiles 32 that make up the window frame 30 are all made of thermally broken aluminum profiles 33, thus forming a structure that makes it difficult to transfer heat to the indoor side, effectively blocking the heat transfer between the indoor and outdoor sides, achieving thermal insulation, improving the overall thermal insulation performance of the micro-ventilation window 10, effectively reducing the overall heat loss of the micro-ventilation window 10, improving the overall energy-saving effect of the micro-ventilation window 10, and contributing to the promotion of energy conservation and environmental policies.

[0077] Furthermore, both the ventilation assembly 40 and the screen 50 are fixed to the vertical frame profile 31 of the window frame 30. The vertical frame profile 31 is a thermally broken aluminum profile 33 with a thermal break bridge 333. The ventilation assembly 40 and the screen 50 are then fixed to the vertical frame profile 31 by additional fixing fittings 60. For example... Figure 6 and Figure 7As shown, the fixing accessory 60 and the window frame 30 are separate structures, that is, the fixing accessory 60 is a component independent of the window frame 30; the fixing accessory 60 is fixedly connected to the outdoor side profile 331 or the indoor side profile 332 of the vertical frame profile 31 to realize the fixed installation of the fixing accessory 60 on the vertical frame profile 31; the fixing accessory 60 includes a first fixing part 61 distributed on the outer periphery of the ventilation component 40 and a second fixing part 62 distributed on the outer periphery of the screen window 50. The ventilation component 40 is fixed to the first fixing part 61 to realize the fixed installation of the ventilation component 40 on the fixing accessory 60, and the screen window 50 is fixed to the second fixing part 62 to realize the fixed installation of the screen window 50 on the fixing accessory 60. Thus, both the ventilation component 40 and the screen 50 are fixed to the vertical frame profile 31 by the fixing accessories 60. Since the fixing accessories 60 and the vertical frame profile 31 are separate structures, the setting of the fixing accessories 60 will not interfere with the fixing of the outdoor side profile 331 and the thermal break bridge 333 in the vertical frame profile 31, or the fixing of the indoor side profile 332 and the thermal break bridge 333. This effectively avoids interference with the assembly of the thermally broken aluminum profile 33 that constitutes the window frame 30 (especially the vertical frame profile 31), while also achieving the fixed installation of the ventilation component 40 and the screen 50. Ultimately, this makes it easy to fix the ventilation component 40 and the screen 50 within the thermally broken aluminum profile 33.

[0078] Therefore, the micro-ventilation window 10 involved in this application not only utilizes thermally broken aluminum profile 33 to provide good thermal insulation performance, but also provides ventilation and insect prevention functions through the ventilation component 40 and screen 50. In particular, the installation of a separate fixing accessory 60 from the window frame 30 makes it easy to fix the ventilation component 40 and screen 50 within the window frame 30 made of thermally broken aluminum profile 33. Ultimately, the micro-ventilation window 10 involved in this application has at least good thermal insulation performance, ventilation function, and insect prevention function, effectively enhancing the product competitiveness of the micro-ventilation window 10.

[0079] Preferably, in the thermally broken aluminum profiles 33 of the vertical frame profile 31 and the horizontal frame profile 32 constituting the window frame 30, the outdoor side profile 331 and the thermally broken bridge 333, as well as the indoor side profile 332 and the thermally broken bridge 333, are all fixed by riveting, which is simple to implement and the fixing is reliable.

[0080] Furthermore, such as Figures 1 to 3 ,or Figures 4 to 6As shown, the micro-ventilation window 10 also includes an outdoor side panel 80 that is closable and installed on the outdoor side of the window frame 30, and an indoor side panel 90 that is closable and installed on the indoor side of the window frame 30; the ventilation component 40 is located on the outdoor side of the screen window 50, and the ventilation component 40 is located on the indoor side of the outdoor side panel 80, while the screen window 50 is located on the outdoor side of the indoor side panel 90. Preferably, the left edge of the outdoor side panel 80 is rotatably installed on the outdoor side of the left vertical frame profile 31 in the window frame 30, and the left edge of the indoor side panel 90 is rotatably installed on the indoor side of the left vertical frame profile 31 in the window frame 30. By rotating the outdoor side panel 80 and the indoor side panel 90, the outdoor side panel 80 and the indoor side panel 90 can be opened and closed, thereby conveniently opening or closing the micro-ventilation window 10.

[0081] like Figures 1 to 3 When the micro-ventilation window 10 shown is in the closed state, the outdoor side panel 80 is closed and abuts against the outdoor side of the window frame 30, and the indoor side panel 90 is closed and abuts against the indoor side of the window frame 30. The ventilation component 40 and the screen 50 are covered by the outdoor side panel 80 and the indoor side panel 90 and hidden inside the window frame 30, so that neither the ventilation component 40 nor the screen 50 is exposed from the indoor or outdoor side of the micro-ventilation window 10, and both are built into the window frame 30. On the one hand, when the micro-ventilation window 10 is closed, both the indoor and outdoor sides are flat, with the ventilation component 40 and the screen 50 hidden between the outdoor side panel 80 and the indoor side panel 90, achieving a clean design and improving the appearance of the micro-ventilation window 10. On the other hand, when the outdoor side panel 80 is closed, it covers the outdoor side of the ventilation component 40, and when the indoor side panel 90 is closed, it covers the indoor side of the screen 50, protecting the ventilation component 40 and the screen 50 from contamination in this state. The ventilation component 40 and the screen 50 are not easily soiled, reducing the cleaning time of the ventilation component 40 and the screen 50. Furthermore, the outdoor side panel 80 and the indoor side panel 90 are preferably both made of aluminum panels. Combined with the outdoor side profile 331 and the indoor side profile 332 of aluminum profiles, the micro-ventilation window 10 is entirely made of aluminum when closed, thus achieving a smooth, flat, and aesthetically harmonious design for both the interior and exterior of the building where the micro-ventilation window 10 is located, enhancing the building's aesthetic design.

[0082] After rotating the outdoor side panel 80 of the micro-ventilation window 10 forward when it is closed, as follows: Figure 5 As shown, when the outdoor side panel 80 is opened, a narrow, elongated vertical slit is formed between the right side of the outdoor side panel 80 and the window frame 30, allowing the ventilation assembly 40 to be exposed on the outdoor side of the micro-ventilation window 10; when the indoor side panel 90 in the micro-ventilation window 10 is rotated backward in the closed state, as... Figure 4As shown, the interior side panel 90 is opened, and a narrow, elongated vertical slit is formed between the right side of the interior side panel 90 and the window frame 30. This narrow vertical slit allows the screen 50 to be exposed on the interior side of the micro-ventilation window 10. Therefore, when both the exterior side panel 80 and the interior side panel 90 are opened, as... Figure 6 As shown, when the micro-ventilation window 10 is open, the narrow vertical slit between the outdoor side panel 80 and the window frame 30 effectively absorbs the wind along the building's exterior wall. This wind then flows into the room through the ventilation assembly 40, the screen 50, and the narrow vertical slit between the indoor side panel 90 and the window frame 30, effectively providing natural ventilation. Simultaneously, even when both the outdoor side panel 80 and the indoor side panel 90 are open, the openings formed between the outdoor side panel 80 and the window frame 30, and between the indoor side panel 90 and the window frame 30, are narrow vertical slits, effectively absorbing outside air while also providing some rain protection.

[0083] Furthermore, when the micro-ventilation window 10 is closed, the screen 50 is covered by the outdoor side panel 80 and the indoor side panel 90, making the screen 50 a built-in installation structure within the window frame 30, thus preventing the screen 50 from getting dirty. When the micro-ventilation window 10 is open, the screen 50 can be exposed from the indoor side of the micro-ventilation window 10, allowing users to easily clean and maintain the screen 50 indoors. Therefore, the micro-ventilation window 10 involved in this application takes into account aesthetic design, insect prevention, and ease of maintenance of the screen 50.

[0084] Furthermore, such as Figure 1 and Figure 3 ,as well as Figure 4 and Figure 6As shown, the micro-ventilation window 10 also includes a handle 110 and a linkage mechanism 120. The handle 110 is connected to the outdoor side panel 80 and the indoor side panel 90 via the linkage mechanism 120. The indoor side panel 90 is operated via the handle 110, and the linkage mechanism 120 enables the linkage between the outdoor side panel 80 and the indoor side panel 90: when the user holds the handle 110 and pulls the indoor side panel 90 backward, the indoor side panel 90 rotates backward around its axis of rotation with respect to the window frame 30. Under the action of the linkage mechanism 120, the outdoor side panel 80 simultaneously rotates forward around its axis of rotation with respect to the window frame 30, thus simultaneously rotating the outdoor side panel 80 and the indoor side panel 90 away from the window frame 30, thereby opening the micro-ventilation window. 10; Conversely: When the user holds the handle 110 and pushes the interior side panel 90 forward, the interior side panel 90 rotates forward around its axis of rotation with respect to the window frame 30. Under the action of the linkage mechanism 120, the exterior side panel 80 simultaneously rotates backward around its axis of rotation with respect to the window frame 30, so that the exterior side panel 80 and the interior side panel 90 rotate simultaneously toward the window frame 30 until the exterior side panel 80 abuts against the exterior side of the window frame 30 and the interior side panel 90 abuts against the interior side of the window frame 30, thereby closing the micro-ventilation window 10. The assembly structure between the handle 110, the linkage mechanism 120, the exterior side panel 80, and the interior side panel 90 is prior art, and can be found in the relevant structure of the door and window disclosed in Japanese Patent Document No. JP2018159209A, so it will not be described in detail here.

[0085] Preferably, when the micro-ventilation window 10 is in the closed state, such as Figure 3 As shown, the exterior side panel 80 abuts against the exterior side of the window frame 30, and at least a portion of it is housed within an opening on the exterior side of the window frame 30. The interior side panel 90 abuts against the interior side of the window frame 30, and at least a portion of it is housed within an opening on the interior side of the window frame 30. Both the exterior side panel 80 and the interior side panel 90 are flat, flat structures, thus achieving a clean design and improving the appearance of the micro-ventilation window 10. Furthermore, as... Figure 1 and Figure 4 As shown, the interior side panel 90 has a forward-recessed mounting groove 91 on its rear surface facing the interior. The handle 110 is accommodated in the mounting groove 91 and does not protrude rearward from the interior side panel 90. The handle 110 itself has a compact and small structure, which can be flatly stored in the mounting groove 91 of the interior side panel 90, thus achieving a clean design and improving the appearance of the micro-ventilation window 10. The handle 110 is preferably a metal handle, which enhances the overall texture of the micro-ventilation window 10. The installation height of the handle 110 on the interior side panel 90 can be determined according to the user's age, physical ability, and the installation height of the micro-ventilation window 10 on the exterior wall of the building to provide the best user experience.

[0086] Preferably, in the micro-ventilation window 10, the exterior side panel 80 and the interior side panel 90 are each rotatably mounted to the window frame 30 on their respective left edges. Therefore, when both the exterior side panel 80 and the interior side panel 90 are opened, as... Figure 6 As shown, the exterior side panel 80 and the interior side panel 90 form a V-shaped structure with the opening facing right. Furthermore, when the exterior side panel 80 is fully opened, the maximum distance D between it and the window frame 30 does not exceed 50mm, improving safety. Of course, in other embodiments, both the exterior side panel 80 and the interior side panel 90 may be rotatably mounted on the right vertical frame profile 31 of the window frame 30 along their respective right edges.

[0087] Furthermore, such as Figure 6 and Figure 7 As shown, the ventilation component 40 is positioned near the outdoor side of the window frame 30, and the screen 50 is positioned near the indoor side of the ventilation component 40. Therefore, in the front-to-back direction, both the ventilation component 40 and the screen 50 are relatively close to the outdoor side profile 331 of the vertical frame profile 31. Based on this, it is preferable that both the ventilation component 40 and the screen 50 are fixed to the inner periphery of the outdoor side profile 331 of the vertical frame profile 31 using fixing accessories 60. While considering the thermal insulation performance of the window frame 30, this arrangement allows the ventilation component 40 and the screen 50 to be easily fixed to the inner periphery of the thermally broken aluminum profile 33, and also ensures that both are concealed and fixed within the window frame 30. When the micro-ventilation window 10 is closed, neither the ventilation component 40 nor the screen 50 is visible, improving the aesthetics.

[0088] like Figure 6 and Figure 7 As shown, there is a pair of fixing accessories 60. The pair of fixing accessories 60 are arranged on the left and right sides of the screen window 50 along the width direction (i.e., the left and right direction), so that the screen window 50 and the ventilation component 40 are reliably fixed within the window frame 30, thereby improving the overall structural strength of the micro-ventilation window 10. The fixing structure of the left and right fixing accessories 60 with the outdoor side profile 331 of the vertical frame profile 31, the screen window 50 and the ventilation component 40 is a left-right symmetrical structure. The following description takes the right fixing accessory 60 with the outdoor side profile 331 of the vertical frame profile 31, the screen window 50 and the ventilation component 40 as an example. The cross-sectional shape of the fixing accessory 60 is roughly I-shaped. The first fixing part 61 and the second fixing part 62 are arranged side by side along the width direction of the screen window 50. The first fixing part 61 is located on the side of the second fixing part 62 away from the screen window 50. The first fixing part 61 is a flat structure. The second fixing part 62 is a U-shaped structure with its opening facing the screen window 50 and has an abutting part 621. The abutting part 621 is also a flat structure. The first fixing part 61 and the abutting part 621 are flush and both abut against the indoor side of the ventilation component 40, so that the front surface of the fixing accessory 60 is flat and it contacts and abuts against the indoor end face of the ventilation component 40, thereby facilitating the fixing of the ventilation component 40 and improving the installability of the ventilation component 40.

[0089] Furthermore, the preferred fixing structure between the fixing fitting 60 and the outdoor side profile 331 of the vertical frame profile 31, and the ventilation assembly 40 is as follows: Figure 6 and Figure 7 As shown, a profile fixing part 34 extends integrally from the outdoor profile 331 of the vertical frame profile 31. The ventilation component 40, the first fixing part 61, and the profile fixing part 34 are stacked sequentially from front to back. The ventilation component 40, the first fixing part 61, and the profile fixing part 34 are fixed together by at least one locking screw 70. When there are multiple locking screws 70, they are arranged sequentially from top to bottom. In this way, the locking screws 70 fasten the ventilation component 40, the fixing accessory 60, and the vertical frame profile 31, making the fixing structure of the ventilation component 40, the fixing accessory 60, and the vertical frame profile 31 simple and easy to implement.

[0090] Preferably, such as Figure 6 and Figure 7 As shown, the profile fixing part 34 extending from the outdoor profile 331 of the vertical frame profile 31 is a bent structure. The profile fixing part 34 includes a first flat plate part 341, a bent part 342, and a second flat plate part 343 connected in sequence along the direction away from the outdoor profile 331. The first flat plate part 341 and the second flat plate part 343 both extend straight in the left and right direction. The bent part 342 extends straight backward from the end of the first flat plate part 341 away from the outdoor profile 331. The profile fixing part 34 bends at the bent part 342. A fitting groove 35 is formed between the bent part 342 and the second flat plate part 343. The opening of the fitting groove 35 faces the outdoor side, that is, towards the ventilation component 40. The first fixing part 61, which is a flat plate structure, is embedded in the fitting groove 35 in the fixing accessory 60. After the first fixing part 61 is fitted with the profile fixing part 34, the front surface of the first fixing part 61 is flush with the front surface of the first flat plate part 341, which facilitates the subsequent installation of the ventilation component 40. After the ventilation component 40 is installed, a portion of the first flat plate part 341 abuts against the indoor side of the ventilation component 40. In this way, the portion of the first flat plate part 341 of the outdoor profile 331 of the vertical frame profile 31, as well as the first fixing part 61 and the second fixing part 62 of the fixing accessory 60, all abut against the indoor side of the ventilation component 40 and are in surface contact with the ventilation component 40, improving the installability of the ventilation component 40 and facilitating its fixed installation. Meanwhile, the profile fixing part 34 forms a fitting groove 35 by bending, which can play a certain positioning role when the first fixing part 61 is fixed. At the same time, after the ventilation component 40 is fixed, the first fixing part 61 fits between the ventilation component 40 and the second flat plate part 343, which also improves the installability of the fixing accessory 60.

[0091] Furthermore, the preferred fixing structure between the fixing accessory 60 and the screen 50 is as follows: Figure 6 and Figure 7As shown, the second fixing part 62 is a U-shaped structure with its opening facing the screen window 50. The second fixing part 62 has a fixing groove 63 with its opening facing the screen window 50. The screen window 50 includes a screen body 51 and a pair of screen frames 52 fixed along the width direction of the screen body 51 on the left and right sides of the screen body 51. The screen frames 52 are elastically deformable. Preferably, the screen frames 52 are injection molded parts, and the material can be PVC or other materials, facilitating the production and manufacturing of the screen frames 52. When fixing the screen window 50 to the fixing accessory 60, it is only necessary to press the screen frame 52 into the fixing groove 63 of the second fixing part 62. Then, the screen frame 52 is snapped into place (i.e., tightly fixed) in the fixing groove 63 of the second fixing part 62 by its rebound. This structure is simple and easy to implement, improving the installability of the screen window 50 and facilitating its fixed installation.

[0092] Preferably, such as Figure 6 and Figure 7 As shown, the fixing accessory 60 has a first limiting protrusion 64 fixed on the groove wall of the fixing groove 63, and a second limiting protrusion 53 is provided on the outer peripheral surface of the screen frame 52. The first limiting protrusion 64 abuts against one side of the second limiting protrusion 53 in the direction in which the screen frame 52 disengages from the fixing groove 63; that is, the first limiting protrusion 64 on the left fixing accessory 60 abuts against the right side of the second limiting protrusion 53 on the left side of the screen frame 52, and the first limiting protrusion 64 on the right fixing accessory 60 abuts against the left side of the second limiting protrusion 53 on the right side of the screen frame 52. In this way, after the screen 50 is fixed, the abutting cooperation of the first limiting protrusion 64 and the second limiting protrusion 53 restricts the second limiting protrusion 53 from disengaging from the fixing groove 63, which in turn restricts the screen frame 52 from disengaging from the fixing groove 63 of the fixing accessory 60, thereby improving the fixing reliability between the screen frame 52 and the fixing accessory 60.

[0093] Preferably, the fixing accessory 60 with the above structure is an aluminum profile and is an integrally molded part, which facilitates the production and manufacturing of the fixing accessory 60, and also gives the fixing accessory 60 itself good structural strength, thereby improving the fixing reliability of the ventilation component 40 and the screen window 50.

[0094] Furthermore, the ventilation component 40 in this application is also waterproof, preventing rainwater from entering the room even when the micro-ventilation window 10 is open. A preferred structure for the ventilation component 40 is as follows: Figure 8 and Figure 9As shown, the ventilation assembly 40 includes several louvers 41 that are horizontally arranged side by side and fixedly connected in the left-right direction. A ventilation channel 42 connecting the indoor and outdoor spaces is formed between two adjacent louvers 41. In the direction of outdoor air flow into the indoor space in the ventilation channel 42, the first section of the ventilation channel 42 is an air inlet section 421 with an opening facing the outdoor side, so as to allow outdoor air to flow into the indoor space. The louver 41 includes a transverse main profile portion 411 and a vertical profile portion 412 integrally extended from the surface of the transverse main profile portion 411; among the plurality of louvers 41: the transverse main profile portions 411 of some louvers 41 are distributed on the outdoor side of the ventilation assembly 40, and the vertical profile portions 412 thereon extend backward toward the indoor side; the transverse main profile portions 411 of another portion of louvers 41 are distributed on the indoor side of the ventilation assembly 40, and the vertical profile portions 412 thereon extend forward toward the outdoor side; the vertical profile portions 412 are located in the ventilation channel 42, and the indoor side of the air inlet section 421 of the flow channel is blocked by the transverse main profile portions 411 distributed on the indoor side of the ventilation assembly 40. Thus, the arrangement of several horizontal main profile sections 411 distributed on the indoor side of the ventilation component 40, several horizontal main profile sections 411 distributed on the outdoor side of the ventilation component 40, and several vertical profile sections 412 causes the ventilation channel 42 to extend in a meandering manner; that is, along the direction of outdoor air flow into the indoor air in the ventilation channel 42, the ventilation channel 42 first extends backward, then extends to the left or right, then extends forward, then extends to the left or right again, and finally extends backward to the screen. With this configuration, the ventilation component 40 not only achieves ventilation but also effectively suppresses rainwater intrusion into the room from the outside through the indoor side transverse main profile 411 distributed in the air inlet section 421 of the flow channel, ensuring the water tightness of the micro ventilation window 10. Even if rainwater enters the air inlet section 421 at an angle due to the wind on rainy days, the ventilation component 40 can still suppress the rainwater from flowing into the room, effectively achieving natural indoor ventilation on rainy days. It still has a better performance when the user is not indoors or forgets to close the micro ventilation window 10.

[0095] Preferably, the ventilation assembly 40 further includes a top fixing plate disposed on the top of several louvers 41, a bottom fixing plate disposed on the bottom of several louvers 41, and several intermediate fixing plates. The upper ends of several louvers 41 are fixedly connected to the top fixing plate by screws, and the lower ends of several louvers 41 are fixedly connected to the bottom fixing plate by screws. At the middle position of the louvers 41, two adjacent louvers 41 are fixedly connected by screws through the intermediate fixing plate, thereby realizing the fixed connection of several louvers 41.

[0096] The micro-ventilation window 10 involved in this application has multiple application scenarios depending on ventilation needs, to meet the coordinated design of buildings for any purpose. For example: Figure 10 As shown, the micro-ventilation window 10 can be used alone to form a single-window configuration. For example: Figures 11 to 13As shown, the micro ventilation window 10 is used in conjunction with other existing windows 20 to form a connected window configuration; Figure 11 In the application example shown, a micro ventilation window 10 is configured on one side (left side only or right side only) of an existing single window 20. Figure 12 In the application example shown, a micro ventilation window 10 is configured on both sides (left and right sides) of a single existing window 20; Figure 13 In the application example shown, there are multiple existing windows 20, and a micro-ventilation window 10 is configured between two adjacent existing windows 20. When the micro-ventilation window 10 is combined with other existing windows 20 to form a connected window structure, it simultaneously meets the requirements of a large view and natural indoor ventilation.

[0097] In summary, in the micro-ventilation window 10 involved in this application, the window frame 30 adopts thermally broken aluminum profile 33 with good thermal insulation properties, and the ventilation component 40 and screen window 50 are fixedly installed in the window frame 30 through the fixing accessories 60 with a split structure, ensuring ventilation, insect prevention and water tightness. Ultimately, the micro-ventilation window 10 has good thermal insulation performance, ventilation function, insect prevention function and waterproof function, effectively enhancing the product competitiveness of the micro-ventilation window 10.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
