Description

Technical Field

[0001] The utility model relates to the technical field of window accessories, in particular to a waterproof and breathable membrane connector. Background Art

[0002] In modern building design and construction, windows serve as a critical link between interior and exterior, and their installation quality directly impacts a building's thermal insulation, water resistance, and ventilation. Traditional window installation methods often employ simple sealing strips or foam filling to address the gap between the window opening and the frame. While this approach can block rainwater to a certain extent, it often neglects the need for air permeability, leading to problems such as mold and moisture accumulation around the window, impacting the health and comfort of the living environment. Furthermore, with the development of the construction industry and improvements in people's living standards, window installation requirements are becoming increasingly stringent, demanding not only excellent waterproofing but also effective ventilation between indoor and outdoor air, maintaining fresh and clean indoor air. Traditional methods for addressing gaps have significant shortcomings in this regard, failing to meet the high standards demanded by modern building window installation. Consequently, technological advancements have led to the development of waterproof and breathable membranes, which offer both excellent waterproofing and excellent air permeability. These membranes can be bonded between the window opening and the window opening, improving the waterproofing and air permeability of the window after installation.

[0003] However, if the waterproof breathable membrane is directly bonded to the corner of the window hole, the waterproof breathable membrane will have large wrinkles, which may easily cause the window to be installed unevenly. This position may easily cause the window to leak later, increasing the chance of repair and the difficulty of later maintenance. Utility Model Content

[0007] A second outer groove is formed on the outer side of the second connecting member and fits the window hole, and two surfaces of the second connecting member that fit the window hole are perpendicular to each other.

[0008] Preferably, the inner side of the first connecting member is integrally formed to form a first inner groove, and the first inner groove is inclined from one side close to the second connecting member to the other side to form a slope, and the horizontal height of the slope close to the second connecting member is higher than the horizontal height of the other side.

[0009] Preferably, the inner side of the second connecting member is integrally formed to form a second inner groove, and a side of the second inner groove close to the window forms vertical surfaces perpendicular to each other.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Implementation Method 1

[0022] The utility model provides Figure 1-Figure 4 The waterproof breathable membrane connector shown includes an integrally formed first connector 1 and a second connector 3. The first connector 1 and the second connector 3 are fixedly connected, and a first outer groove 6 is formed on the outer side of the first connector 1 to fit the window sill. The two surfaces of the first connector 1 that fit the window sill are perpendicular to each other.

[0023] Furthermore, a second outer groove 4 that fits the window hole is formed on the outer side of the second connecting member 3 , and the two surfaces of the second connecting member 3 that fit the window hole are perpendicular to each other.

[0024] As can be seen from the above, when using, when the device needs to be installed, the waterproof breathable film is glued to the window hole. After the waterproof breathable film is glued, the device is glued to the corner of the window hole, and then the window is glued to the window hole to complete the installation of the window. There is no need to glue the waterproof breathable film to the corner of the window hole to avoid wrinkles on the waterproof breathable film.

[0025] refer to Figure 1-Figure 3 As shown, in order to allow the water to be discharged faster, as shown Figure 1-Figure 2 As shown, the inner side of the first connecting member 1 is integrally formed to form a first inner groove 2, and the first inner groove 2 is inclined from one side close to the second connecting member 3 to the other side to form a slope, and the horizontal height of the slope close to the second connecting member 3 is higher than the horizontal height of the other side.

[0026] Furthermore, in order to make the device fit the window better, e.g. Figure 1-Figure 2 As shown, the inner side of the second connecting member 3 is integrally formed to form a second inner groove 5, and the side of the second inner groove 5 close to the window forms vertical surfaces perpendicular to each other.

[0027] Implementation Method 2

[0028] This embodiment provides a specific waterproof and breathable membrane connector structure. First, the first connector 1 and the second connector 3 are integrally formed using injection molding technology, ensuring a stable structure and a tight connection. The outer side of the first connector 1 is designed with a first outer groove 6. The shape and size of this groove match the outer edge of the window sill, ensuring that the connecting angle fits tightly against the window sill and prevents moisture penetration. Furthermore, the two surfaces of the first connector 1 that contact the window sill are perpendicular to each other to accommodate the common right-angle structure of window sills.

[0029] The outer side of the second connector 3 is designed with a second outer groove 4, whose shape and size match the inner edge of the window opening, so that the connecting corner can fit tightly around the window opening, enhancing the waterproof effect. Similarly, the two surfaces of the second connector 3 that fit the window opening are also perpendicular to each other.

[0030] A first inner groove 2 is integrally formed inside the first connector 1. This groove slopes from one side near the second connector 3 toward the other side, forming a slope. The slope's angle is optimized to ensure smooth drainage of rainwater and prevent water accumulation. The slope's height near the second connector 3 is higher than the other side, helping to direct water flow.

[0031] A second inner groove 5 is integrally formed on the inner side of the second connecting member 3 , and a side thereof close to the window forms vertical surfaces perpendicular to each other. This design can facilitate the installation of a waterproof and breathable membrane and ensure the stability of the membrane.

[0032] Implementation Method 3

[0033] This embodiment provides another structure for a waterproof, breathable membrane connector. Similar to the first embodiment, the first connector 1 and the second connector 3 are also integrally formed using injection molding technology. However, in this embodiment, the design of the first outer groove 6 and the second outer groove 4 is more flexible and can be customized to the shape and size of different window sills and window openings to accommodate a wider range of installation requirements.

[0034] The two windowsill-fitting surfaces of the first connector 1 are still perpendicular to each other, but the slope angle of the first inner groove 2 can be adjusted according to actual needs to achieve the best drainage effect. At the same time, drainage holes can be set at the bottom of the first inner groove 2 to further speed up drainage.

[0035] The two surfaces of the second connector 3 that mate with the window opening are also perpendicular to each other. The design of the second inner groove 5 can also be customized according to the shape and size of the window. To enhance the waterproof effect, a sealing strip or sealant can be provided on the vertical surface of the second inner groove 5 to ensure a tight fit between the waterproof and breathable membrane and the connecting corner.

[0036] Implementation Method 4

[0037] This embodiment provides a more complex but more powerful waterproof breathable membrane connector structure. In addition to all the features of the first and second embodiments, this embodiment also provides a reinforcing rib between the first connector 1 and the second connector 3 to enhance the overall strength and stability of the connection angle.

[0038] At the same time, the design of the first outer groove 6 and the second outer groove 4 has also been optimized, using a softer material and a shape that better fits the window sill and window opening to ensure that the window sill and window opening will not be damaged during the installation process.

[0039] In addition, this embodiment also includes a filter layer within the first inner tank 2 and the second inner tank 5 to filter out impurities and dirt in rainwater, preventing clogging and damage to the waterproof breathable membrane. The filter layer can be made of materials such as non-woven fabric and filter mesh, and the specific material and thickness can be selected according to actual needs.

[0040] Implementation Method Five

[0041] This embodiment provides an adjustable waterproof breathable membrane connector structure. In the design of the first outer groove 6 and the second outer groove 4, this embodiment also adopts a more flexible and customizable solution to adapt to window sills and window openings of different shapes and sizes.

[0042] Implementation Method 6

[0043] This embodiment focuses on the material selection and surface treatment of the waterproof and breathable membrane connector, aiming to enhance its durability and aesthetics. The connector body is constructed from high-strength, corrosion-resistant polymer materials, such as modified polypropylene (PP) or polyvinyl chloride (PVC). These materials not only offer excellent mechanical properties but also resist UV radiation and chemical corrosion, ensuring long-term stability in outdoor environments.

[0044] A layer of weather-resistant paint is applied to the exterior surfaces of the first and second connectors 1 and 3. This paint effectively resists erosion from wind and rain, prevents aging and fading, and smoothes the connection angles for easier cleaning and maintenance. Furthermore, the paint color can be customized to suit the architectural style and customer preferences, enhancing the overall aesthetics of the building.

[0045] The interiors of the first and second inner tanks 2 and 5 are treated with a micro-nanoscale anti-stick coating. This coating effectively prevents the adhesion of dust, dirt, and other impurities, maintaining the cleanliness and efficient ventilation of the breathable membrane. The coating also has a certain self-cleaning function, allowing rainwater to wash away most surface stains.

[0046] Combine Figure 1 and Figure 4 As shown, the first connector 1 is 100mm long, 60mm wide, and 100mm high; the second connector 3 is 100mm long and 100mm high; the shortest straight-line distance between the horizontal plane of the second inner groove 5 and the bottom of the second connector 3 is 24mm, and the width of the second inner groove 5 is 20mm. Within this dimension range, the waterproof breathable membrane connector achieves optimal connection, effectively preventing wrinkles in the waterproof breathable membrane while also preventing uneven window installation. This position also prevents leaks later in the window, minimizing the risk of maintenance.

[0047] Through the description of the above different embodiments, it can be seen that the waterproof and breathable membrane connector provided by the present invention not only solves the waterproof and breathable problems in traditional window installation, but also provides a more efficient, convenient and sustainable solution for modern buildings through material innovation, intelligent design and the application of green environmental protection concepts.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
