Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a water-blocking structure for an aluminum alloy window sill. Background Technology

[0002] Currently, roofs typically incorporate venting channels within the insulation layer. However, these channels only have vents, lacking ventilation openings. This structure results in moisture evaporating from within the roof by relying on humidity balance with the outside environment. When the outdoor air humidity is lower than the roof's internal structure, the moisture shifts outward. Because there are only outlets and no inlets, gas exchange cannot occur, leading to low efficiency in moisture transfer. This process takes a considerable amount of time and makes it difficult to thoroughly dry the roof insulation and the sloping layer.

[0003] Furthermore, most exhaust vents lack insect-proof design, allowing mosquitoes, spiders, and other small animals to enter the exhaust pipes. Insect eggs hatch and form nests, or fallen leaves or dust clog the pipes, causing exhaust vent malfunctions. If ventilation openings are installed in the exhaust ducts, the same problem needs to be addressed. Even with ventilation openings, birds or other small animals can enter and nest, damaging the roof insulation layer. Utility Model Content

[0004] The purpose of this invention is to provide an insect-proof structure for the ventilation openings on the wall side of the roof insulation layer to prevent insects and birds from entering.

[0005] The purpose of this utility model is achieved as follows.

[0006] An insect-proof structure for a wall-side ventilation opening in a roof insulation layer includes a ventilation opening body. The rear end of the ventilation opening body is provided with an insertion part for insertion into an exhaust duct. The insertion part and the exhaust duct are adapted to each other. The front end of the ventilation opening body is provided with an air inlet. An insect-proof net assembly is detachably provided in the inner cavity of the front end of the ventilation opening body near the air inlet. The insect-proof net assembly includes a mesh frame and an insect-proof screen set on the mesh frame. The insect-proof net assembly is vertically placed in the inner cavity of the ventilation opening body. External airflow enters from the air inlet, passes through the mesh of the insect-proof screen, and enters the exhaust duct from the inner cavity of the ventilation opening body.

[0007] Furthermore, the top surface of the vent body extends downward to a mounting part, the mounting part has a slot along the width direction, and the bottom surface of the vent body has insertion holes on both sides. The insertion holes and slots are aligned in the vertical direction. The width of the mesh frame is equal to the width of the vent body's internal cavity. The bottom sides of the mesh frame have pins, the top of the mesh frame is inserted into the slot, and the pins are inserted into the corresponding insertion holes.

[0008] The insect netting components are simple and easy to install and remove, facilitating future maintenance and replacement.

[0009] Furthermore, an installation gap is left between the slot and the top surface of the mesh frame. The top of the mesh frame is inserted into the slot at an angle. The mesh frame moves upward along the slot to eliminate at least part of the installation gap, so that the pin part of the mesh frame is inserted into the corresponding socket. The mesh frame moves downward to leave an installation gap until the bottom of the mesh frame sits on the bottom surface of the vent body cavity, while the top of the mesh frame remains in the slot.

[0010] The installation gaps facilitate the installation and removal of the wire mesh frame, ensuring a secure installation.

[0011] Furthermore, the top of the inner end face of the mesh frame is provided with a first guide slope that slopes inward from top to bottom. The first guide slope guides the top of the mesh frame to be inserted into the slot at an angle. The outer end face of the pin is provided with a second guide slope that slopes inward from top to bottom. The second guide slope guides the pin to disengage from the insertion hole.

[0012] The wire mesh frame is easy to install and remove.

[0013] Furthermore, a handle is provided on the outer end face of the mesh frame, and the handle is located at the lower part of the mesh frame.

[0014] The handle makes it easy to move the mesh frame, preventing damage to the insect-proof screen.

[0015] Furthermore, the handle is in the shape of a straight line, with both ends of the handle connected and fixed to the side frame of the mesh frame, and the middle of the handle is mounted on the insect-proof screen.

[0016] The handle makes it easy to push the mesh frame up and remove it.

[0017] Furthermore, both the wire frame and the insect-proof screen are made of PVC. They have a long service life and are rust-resistant.

[0018] Furthermore, the mesh size of the insect-proof screen is 16-32 mesh.

[0019] It effectively prevents insects such as mosquitoes and spiders from entering the exhaust pipe.

[0020] The inner wall of the mesh frame is provided with an annular groove, and an elastic sealing element is provided in the annular groove. The edge of the insect-proof screen is clamped between the elastic sealing element and the annular groove.

[0021] The insect screen is designed to be detachable, making it easy to replace later. The elastic seals ensure a tight installation of the insect screen and also provide shock absorption and cushioning, extending the service life of the insect screen.

[0022] This invention's vent body and the original exhaust pipe form an inlet-outlet flow pattern, improving gas exchange efficiency. Highly efficient ventilation and exhaust accelerate the drying process, saving material drying time during construction or roof repair, and thus improving overall construction efficiency. Maintaining long-term ventilation and dryness reduces the probability of roof dismantling and repair. The insect-proof net assembly provides excellent insect protection, preventing damage to the insulation layer. As a fragile component, the insect-proof net assembly facilitates future maintenance and replacement. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1, see Figure 1-10 As shown, a roof insulation layer wall-side ventilation opening insect-proof structure includes a ventilation opening body 1, an insertion part 11 at the rear end of the ventilation opening body 1, an air inlet 10 at the front end of the ventilation opening body 1, and an insect-proof net assembly 4 detachably installed in the inner cavity of the front end of the ventilation opening body 1 near the air inlet 10. The insect-proof net assembly 4 includes a net frame 5 and an insect-proof screen 6 disposed on the net frame 5.

[0033] A mounting portion 2 extends downward from the top surface of the inner cavity of the vent body 1. The mounting portion 2 has a slot 21 along its width. Insertion holes 3 are located on both sides of the bottom surface of the inner cavity of the vent body 1. The insertion holes 3 and the slot 21 are aligned vertically. The width of the mesh frame 5 is equal to the width of the inner cavity of the vent body 1. Insertion pins 54 are located on both sides of the bottom of the mesh frame 5. The top of the mesh frame 5 is inserted into the slot 21, and the insertion pins 54 are inserted into the corresponding insertion holes 3. A mounting gap 50 is left between the slot 21 and the top surface of the mesh frame 5. The top of the mesh frame 5 is inserted into the slot 21 at an angle. The mesh frame 5 moves upward along the slot 21, eliminating at least part of the mounting gap 50, so that the insertion pins 54 of the mesh frame 5 are inserted into the corresponding insertion holes 3. The mesh frame 5 moves downward, leaving the mounting gap 50, until the bottom of the mesh frame 5 rests on the bottom surface of the inner cavity of the vent body 1, while the top of the mesh frame 5 remains within the slot 21. The insect-proof net assembly 4 is placed vertically in the inner cavity of the vent body 1. External airflow enters from the air inlet 10, passes through the mesh of the insect-proof screen 6, and enters the exhaust duct 7 through the inner cavity of the vent body 1.

[0034] To facilitate the installation and disassembly of the wire mesh frame 5, the top of the inner end face of the wire mesh frame 5 is provided with a first guide slope 55 that slopes inward from top to bottom. The first guide slope 55 guides the top of the wire mesh frame 5 to be inserted into the slot 21 at an angle. The outer end face of the pin part 54 is provided with a second guide slope 56 that slopes inward from top to bottom. The second guide slope 56 guides the pin part 54 to disengage from the insertion hole 3.

[0035] The outer end face of the mesh frame 5 is provided with a handle part 53, which is located in the lower part of the mesh frame 5. Specifically, the handle part 53 is in the shape of a straight line, and both ends of the handle part 53 are connected and fixed to the side frame of the mesh frame 5. The middle part of the handle part 53 is mounted on the insect-proof screen 6.

[0036] In this embodiment, both the wire frame 5 and the insect-proof screen 6 are made of PVC. The mesh size of the insect-proof screen 6 is 16-32 mesh. An annular groove 51 is provided on the inner wall of the wire frame 5, and an elastic sealing element 52 is provided within the annular groove 51. The edge of the insect-proof screen 6 is clamped between the elastic sealing element 52 and the annular groove 51. During later maintenance, if the wire frame 5 is undamaged, only the insect-proof screen 6 needs to be replaced. The elastic sealing element 52 is a rubber ring or a silicone ring.

[0037] In this invention, the insertion part 11 and the exhaust duct 7 are shaped to match. The insertion part 11 is inserted into the exhaust duct 7 of the insulation layer 8. The front end of the vent body 1 extends outward from the wall 9, and the top of the front end of the vent body 1 forms a water-blocking eave to prevent water from entering the vent body 1 from the air inlet 10. The insect-proof net assembly 4 is installed inside the part of the vent body 1 that extends outward from the wall 9, facilitating later maintenance of the insect-proof net assembly 4. The insect-proof net assembly 4 can effectively block mosquitoes, birds, and debris from entering the roof, with a significant insect-proof effect. The mesh size of the insect-proof net assembly 4 ensures good ventilation performance and does not significantly obstruct roof ventilation, achieving a balance between efficient insect prevention and good ventilation performance.

[0038] During construction, the insect-proof netting component 4 is installed subsequently, allowing water entering the insulation layer 8 to flow out through the ventilation pipe and avoid lingering in the insulation layer 8.

[0039] This invention can also include a detachable protective grille (not shown in the figure) at the air inlet 10. The protective grille is snap-fitted to the front end of the vent body 1, preventing damage to the insect screen 6 from external forces. Preferably, the protective grille has a cleaning port and an openable cover that covers the cleaning port. After opening the cover, tools can be used to clean the surface of the insect screen. If a thorough cleaning or replacement of the insect screen assembly 4 is required, the protective grille is removed first, followed by the mesh frame 5, allowing the insect screen 6 to be removed for cleaning or replacement.
