Description

Technical Field

[0001] This utility model relates to the field of building vent technology, specifically a building vent structure that is integrated with a curtain wall. Background Technology

[0002] Building ventilation utilizes ventilators to exchange air and control air pollutants. Traditional ventilators use direct air intake and exhaust, which has significant drawbacks. For example, in patent CN220287665U, titled "Integrated Ventilator Structure for Curtain Walls," an air outlet is formed on the rear baffle and connected to an exhaust duct. Multiple exhaust holes are equidistantly arranged on the base plate, with a wire mesh insect screen installed on the inner side of the base plate. This screen prevents dust from entering the air intake and exhaust cavities, improving air cleanliness. The area of ​​the exhaust holes is larger than the cross-sectional area of ​​the exhaust duct, allowing air from the exhaust fan to exit through the outlet at the end of the exhaust duct. The increased area of ​​the exhaust holes reduces exhaust resistance, improves exhaust efficiency, and significantly reduces equipment costs. However, this structure still has the following problems in practical use:

[0003] The above structure places the wire mesh insect net on multiple ventilation holes. The wire mesh insect net can prevent dust from the outside air from entering the air intake and exhaust cavity. However, when the wire mesh insect net needs to be replaced, it cannot be replaced quickly. Moreover, since the wind cap is installed on the outside of the curtain wall and is placed at a high altitude, the replacement time is too long, which also increases the workload of the staff.

[0004] Therefore, we proposed that an integrated curtain wall building wind cap structure can effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated curtain wall building vent structure to solve the problems mentioned in the background art. Currently, when it is necessary to replace the wire mesh insect net, it is not possible to achieve a quick replacement. Furthermore, since the vent is installed on the outside of the curtain wall and is located at a high altitude, the replacement time is too long, which also increases the workload of the staff.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated curtain wall building wind cap structure, including a wall, wherein a curtain wall body is fixedly installed on the upper surface of the wall, and an air inlet and outlet duct is fixedly connected between the curtain wall body and the wall.

[0007] It also includes: a fan is installed at the lower end of the air inlet and outlet duct, and a filter screen is installed at the upper end of the air inlet and outlet duct. A rod is welded and fixed to the lower surface of the filter screen. A locking hole is opened on the outer side of the rod, and a locking rod is engaged inside the locking hole. The locking rod and the air inlet and outlet duct are slidably connected. A return spring is sleeved on the outer side of the locking rod. The outer end of the return spring is fixed to the locking rod, and the inner end of the return spring is fixed to the air inlet and outlet duct.

[0008] Preferably, a sealing ring is bonded to the lower surface of the filter screen, and the sealing ring fits into the air inlet and outlet ducts.

[0009] Preferably, the lever has a "T" shaped structure, and the upper surface of the inner end of the lever is inclined.

[0010] Preferably, an impeller is fixed to the inner wall of the air inlet and outlet duct, and a shaft is connected to the upper surface of the impeller by a bearing. A threaded rod is welded and fixed to the upper end of the shaft, and a fastening nut is bolted to the outer side of the threaded rod.

[0011] Preferably, a connecting block is welded and fixed to the upper end of the shaft, and the connecting block and the cleaning rod form a locking structure, and the cleaning rod is sleeved on the outer side of the threaded rod.

[0012] Preferably, a brush is adhered to the lower surface of the cleaning rod, and the brush is in close contact with the filter screen.

[0013] Preferably, a rain shield is bolted to the upper outer side of the air inlet and outlet duct, and the upper surface of the rain shield is inclined and the rain shield is semi-circular.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the integrated curtain wall building vent structure not only enables quick replacement of the filter screen, reducing the workload of workers, but also allows for the cleaning of insect carcasses and dust on the filter screen surface with a brush, preventing the accumulation of insect carcasses and dust from affecting ventilation. Furthermore, it facilitates the replacement and cleaning of the cleaning rod, making it highly practical. The specific details are as follows:

[0015] (1) By pulling the lever, the lever moves outward, thereby separating the inner end of the lever from the locking hole, thus releasing the limit on the insertion rod, thereby enabling the rapid replacement of the filter screen and reducing the workload of the workers.

[0016] (2) By means of the inclined structure on one side of the clamp rod, the clamp rod can slide outward under force. When the insertion rod moves the clamp hole to be parallel with the clamp rod, the clamp rod is reset by the elastic force of the return spring, so that the inner end of the clamp rod engages with the clamp hole, thereby limiting the position of the insertion rod and achieving the effect of quick installation.

[0017] (3) Furthermore, the sealing effect is achieved by fitting the sealing ring with the air inlet and outlet ducts, thus preventing dust and rainwater from entering through the gaps;

[0018] (4) The impeller rotates by wind, which in turn causes the shaft to rotate. The shaft rotates, which in turn causes the cleaning rod to rotate, allowing it to clean the insect carcasses and dust on the filter screen with a brush, thus preventing the accumulation of insect carcasses and dust from affecting ventilation.

[0019] (5) By rotating the fastening nut off the threaded rod, the limit on the cleaning rod is released. Then, the new cleaning rod is inserted through the threaded rod, so that the connecting block and the cleaning rod fit together. Then, the fastening nut is screwed into the threaded rod, so that the threaded rod limits the cleaning rod and prevents the cleaning rod from coming off. This makes it easier to replace and clean the cleaning rod, and it is practical. Attached Figure Description

[0027] 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.

[0028] Please see Figures 1-6 The present invention provides the following technical solution:

[0029] Example 1: To address the problems in existing technologies where quick replacement of wire mesh insect netting is not possible, and the extended replacement time due to the wind caps being installed on the outside of the curtain wall at a high altitude increases the workload for workers, the following solution is disclosed: A wall 1 is included, with a curtain wall body 2 fixedly installed on its upper surface, and an inlet / outlet duct 3 connecting the curtain wall body 2 and the wall 1; a ventilation fan 4 is installed at the lower end of the inlet / outlet duct 3, and a filter 5 is installed at the upper end of the inlet / outlet duct 3. A rod 6 is welded and fixed to the lower surface of the filter screen 5, and a locking hole 8 is provided on the outer side of the rod 6. A locking rod 9 is engaged inside the locking hole 8. The locking rod 9 is slidably connected to the air inlet and outlet duct 3. A return spring 10 is sleeved on the outer side of the locking rod 9. The outer end of the return spring 10 is fixed to the locking rod 9, and the inner end of the return spring 10 is fixed to the air inlet and outlet duct 3. A sealing ring 7 is bonded to the lower surface of the filter screen 5, and the sealing ring 7 fits with the air inlet and outlet duct 3. The locking rod 9 has a "T" shaped structure, and the upper surface of the inner end of the locking rod 9 is set with an inclined structure.

[0030] The filter screen 5 serves to prevent dust and insects, reducing dust accumulation on the inner wall of the air inlet / outlet duct 3. When the filter screen 5 needs to be removed, pull the lever 9 to move it outwards, separating the inner end of the lever 9 from the locking hole 8, thus releasing the restriction on the insertion rod 6. The filter screen 5 can then be removed for replacement. The new filter screen 5 is then placed at the outer end of the air inlet / outlet duct 3, ensuring the insertion rod 6 engages with the duct 3. When the insertion rod 6 contacts the lever 9, the pressure applied by the lever 6 and the tilt of one side of the lever 9 create a protective barrier. The structure allows the locking rod 9 to slide outward. When the insertion rod 6 moves the locking hole 8 to be parallel with the locking rod 9, the spring force of the return spring 10 causes the locking rod 9 to return to its original position, so that the inner end of the locking rod 9 engages with the locking hole 8, thereby limiting the position of the insertion rod 6 and achieving the installation effect. In addition, a sealing ring 7 is bonded to the inner side of the filter screen 5. The sealing ring 7 and the air inlet and outlet duct 3 fit together to achieve a sealing effect, preventing dust and rainwater from entering through gaps. The above structural design enables the quick replacement of the filter screen 5 and reduces the workload of workers.

[0031] Example 2: Unlike Example 1, this example facilitates the cleaning of insect carcasses and dust on the surface of filter 5. See details below. Figure 1 and Figures 3-6 An impeller 11 is fixed to the inner wall of the air inlet and outlet duct 3, and a shaft 12 is connected to the upper surface of the impeller 11 by a bearing. A threaded rod 13 is welded and fixed to the upper end of the shaft 12, and a fastening nut 15 is bolted to the outer side of the threaded rod 13. A connecting block 14 is welded and fixed to the upper end of the shaft 12, and the connecting block 14 and the cleaning rod 16 form a locking structure. The cleaning rod 16 is sleeved on the outer side of the threaded rod 13.

[0032] The air inlet and outlet duct 3 achieves air exchange and intake through the air exchanger 4. During the air exchange and intake process, the wind will blow the impeller 11 to rotate. The rotation of the impeller 11 will cause the shaft 12 to rotate as well. The rotation of the shaft 12 will drive the cleaning rod 16 to rotate as well. The rotation of the cleaning rod 16 will allow it to clean the insect carcasses and dust on the surface of the filter screen 5 through the brush 17, thus preventing the accumulation of insect carcasses and dust from affecting air exchange.

[0033] Example 3: Unlike Example 2, this example allows for easy replacement of the cleaning rod 16. See details below. Figures 3-4 A brush 17 is attached to the lower surface of the cleaning rod 16, and the brush 17 is tightly attached to the filter screen 5. A rain shield 18 is bolted to the upper outer side of the air inlet and outlet duct 3, and the upper surface of the rain shield 18 is inclined and the rain shield 18 is semi-circular.

[0034] Furthermore, by unscrewing the fastening nut 15 from the threaded rod 13, the restriction on the cleaning rod 16 is released, and the cleaning rod 16 can then be removed for cleaning and replacement. At this time, the filter screen 5 can also be replaced and removed. After the filter screen 5 is installed, the new cleaning rod 16 is inserted through the threaded rod 13, so that the connecting block 14 and the cleaning rod 16 fit together. Then, the fastening nut 15 is screwed into the threaded rod 13, so that the threaded rod 13 restricts the cleaning rod 16 and prevents the cleaning rod 16 from coming off, thus facilitating the replacement and cleaning of the cleaning rod 16. It has good practicality. Moreover, the outer side of the outer end of the air inlet and outlet duct 3 is bolted with a rain shield 18, which can prevent rainwater from entering and achieve the effect of rain protection.
