[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: like Figures 1 to 4As shown, the preferred embodiment of the outdoor seat waterproof vent structure of this utility model includes: vent flange 1, waterproof baffle, louver assembly and vent cap 6.

[0017] The air vent flange 1 is made of 304 stainless steel or galvanized steel sheet and machined into a circular plate structure. A circular through-hole is located in its center. Four bolt holes 11 are evenly spaced on the air vent flange 1 for fixed connection to the civil engineering structure. The waterproof baffle includes a lower cylinder 2 and an upper cylinder 3. Both lower cylinder 2 and upper cylinder 3 are hollow cylindrical structures with equal diameters. The diameter of the circular through-hole of the air vent flange 1 is equal to the outer diameter of the lower cylinder 2. The air vent flange 1 is fixed to the upper part of the lower cylinder 2. The waterproof baffle is made of stainless steel or galvanized steel sheet, and the height of the lower cylinder 2 is greater than the height of the upper cylinder 3. In this embodiment, the air vent flange 1 is located 20mm from the upper end face of the lower cylinder 2.

[0018] The louver assembly includes fixed louvers 4 and adjustable louvers 5. The lower end face of the fixed louver 4 is fixedly connected to the upper end face of the lower cylinder 2, and the upper end face of the fixed louver 4 is fixedly connected to the lower end face of the upper cylinder 3 to form a water-blocking structure. The waterproof baffle can effectively prevent rainwater backflow. The adjustable louver 5 is rotatably connected to the fixed louver 4. By rotating the adjustable louver 5, the size of the air outlet between the blades of the fixed louver 4 can be changed. In this embodiment, triangular air outlets are evenly spaced on the fixed louver 4. The center of the adjustable louver 5 is connected to the center of the fixed louver 4 through a rotating shaft. The shape and size of the adjustable louver 5 match the shape and size of the triangular air outlets. An adjustment handle 51 is provided on the outer side of the adjustable louver. The adjustable louver 5 and the fixed louver 4 are rotatably connected through a rotating shaft. With the design of the adjustment handle 51, the user can manually move the handle according to the actual exhaust volume requirements to flexibly adjust the cross-sectional area of ​​the triangular air outlets. For example, when increased ventilation is needed, the adjustable louvers 5 can be pushed open to one side; when reduced ventilation or to prevent strong winds, they can be retracted to the other side. This dynamic adjustment significantly improves the adaptability of the air vent to different environments (such as low ventilation on rainy days and high ventilation on sunny days).

[0019] The vent cap 6 is fitted onto the outside of the waterproof baffle and is fixedly connected to the upper end face of the vent flange 1. The vent cap 6 has a cylindrical structure, with a diameter larger than the diameter of the upper cylindrical tube 3 but smaller than the outer diameter of the vent flange 1. Four bolt holes 11 are distributed on the outside of the vent cap 6. The top of the vent cap 6 is a circular plate. Based on the exhaust volume requirements, multiple honeycomb-shaped air outlet holes 61 are formed on the vertical cylindrical wall of the vent cap 6. The honeycomb hole diameter is 5-10mm. The design of the vent cap 6 guides external rainwater to the surrounding area, reducing the direct impact of rainwater on the internal structure. This ensures ventilation while preventing large particles of debris from entering, avoiding blockages or rainwater carrying debris infiltration. A horizontal groove 62 is formed on the vent cap 6, and the adjusting handle 51 is movably positioned within the horizontal groove 62.

[0020] Furthermore, a waterproof gasket is installed between the air outlet flange 1 and the civil structure surface to fill the gap between the air outlet flange and the civil structure, preventing rainwater from seeping in along the bolt holes 11 or the edge of the air outlet flange, thus improving the overall sealing performance.

[0021] Example 2: The manufacturing method of this utility model is described below: Step 1: Use 304 stainless steel or galvanized steel sheet to process the air outlet flange 1, and process 4 evenly distributed bolt holes 11 on the air outlet flange 1; Step 2: Processing of waterproof baffles (lower cylinder 2, upper cylinder 3). The waterproof baffles are made of 304 stainless steel or galvanized steel plate. The metal plates are machined into two cylindrical structures. Then, the air vent flange 1 is welded to the lower cylinder 20mm from the upper end face.

[0022] Step 3: Fabrication of the louver assembly. Adjustable louvered air vents are made using 304 stainless steel or galvanized steel sheet. The louver assembly is then assembled, and the airflow is manually adjusted using the handle. One side of the fixed louver 4 is then welded to the upper end of the lower cylinder, and the lower end of the upper cylinder 3 is welded to the other side of the fixed louver 4.

[0023] Step 4: Fabrication of the vent cap. According to the exhaust volume requirements, open the vent cap with honeycomb-shaped air outlet holes of different cross-sectional areas. Put the vent cap 6 on the outside of the waterproof baffle from above, and then weld or fix the vent cap to the air outlet flange by mechanical means.

[0024] Step 5: Connect the air vent flange 1 to the civil structure surface. Apply sealant evenly to the lower end face of the air vent flange 1 (where it contacts the civil structure) or place a pre-cut waterproof gasket. The gasket size should match the outer diameter of the air vent flange. Then align the air vent flange 1 with its installation position on the civil structure surface and secure it with four bolts (tighten the bolts evenly to avoid flange deformation). After installation, check the flange's levelness (error ≤ 2mm) to ensure that rainwater will not seep back due to tilting.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
