[0044] Please see Figures 1 to 3 , Figure 1 A partial sectional view of a building according to an embodiment of this application is shown. Figure 2 It shows Figure 1 A partial front view of a building with concealed rainproof louvers. Figure 3 It shows Figure 1 The schematic diagram shows a partial structure of a ventilation device in a building. One embodiment of this application provides a building 100, including a wall 10 and a ventilation device 20. The wall 10 has wall vents 1, and the ventilation device 20 is installed in the wall vents 1. The ventilation device 20 can ventilate the interior of the building 100. It can have the functions of supplying fresh air to the interior of the building 100, exhausting air from the interior of the building 100, or both supply and exhaust functions. In other words, the ventilation device 20 can be a supply air device, an exhaust air device, or a supply and exhaust air device. The wall vents 1 are correspondingly supply air vents, exhaust air vents, or supply and exhaust air vents, and correspondingly have supply air outlets, exhaust air outlets, or supply and exhaust air outlets.

[0045] In this embodiment, building 100 is an industrial building, specifically, but not limited to, a logistics warehouse or factory plant. It is understood that in other embodiments, building 100 can be a civil building, such as an office building or residential house.

[0046] In this embodiment, the ventilation device 20 includes rainproof louvers 6, a duct structure 30, and an outer inclined baffle 5. The rainproof louvers 6 are disposed in the wall vent 1. The duct structure 30 has a stepped air duct and has an inner stepped surface 32 and a connecting opening 34 located on the inner stepped surface 32. One end of the duct structure 30 is configured to connect to the inner side of the wall vent 1, so that the inner stepped surface 32 faces the wall vent 1. The outer inclined baffle 5 blocks the connecting opening 34. The bottom of the outer inclined baffle 5 is configured to connect to the wall wall of the wall vent 1, the top of the outer inclined baffle 5 is connected to the inner stepped surface 32 and is located above the connecting opening 34, and both sides of the outer inclined baffle 5 are spaced apart from the corresponding inner surfaces of the stepped air duct.

[0047] By connecting the pipe structure 30 inside the wall vent 1, a stepped air duct is formed inside the pipe structure 30, which has an inner stepped surface 32. An outer inclined baffle 5 is set between the inner stepped surface 32 and the wall wall of the wall vent 1. The outer inclined baffle 5 blocks the connecting opening 34 on the inner stepped surface 32, and its side is spaced apart from the corresponding inner surface of the stepped air duct. When strong wind and rain pass through the rainproof louver 6, some water vapor particles in the airflow collide with the outer inclined baffle 5 and settle and are discharged outside the wall. Other water vapor particles enter from the space between the left and right sides of the outer inclined baffle 5 and the inner surface of the pipe structure 30 with the airflow. They collide with each other in the space formed between the outer inclined baffle 5 and the inner stepped surface 32, settle and are discharged outside the wall, so that relatively dry air flows into the connecting opening 34. Therefore, by changing the direction of the airflow passing through the rainproof louvers 6, the ventilation device 20 forces the water vapor particles carried in the airflow to collide at least twice, causing them to settle and be discharged outside the wall, thus improving the rainproof effect against strong winds and rain. This avoids the internal dampness and mold of the wall 10 and the corrosion of the internal air ducts, ensuring the functionality and durability of the building 100. It has significant advantages such as rainproof effect, simple manufacturing, and low cost.

[0048] In this embodiment, the rainproof louver 6 is installed in the wall vent 1 and flush with the outer surface of the wall 10, serving as the first line of defense against rainwater, preventing rainwater from entering the wall vent 1 under normal weather conditions. The outer frame of the rainproof louver 6 is mechanically connected to the wall surface of the wall vent 1, for example, by screws. It should be noted that in other embodiments, the rainproof louver 6 can be installed on the outside of the wall vent 1, that is, its outer frame can be screwed to the outer surface of the wall 10.

[0049] In this embodiment, the outer inclined baffle 5 is disposed inside the rainproof louver 6. Its bottom is configured to connect to the bottom of the wall surface of the wall vent 1, and its top is connected to the upper edge of the inner stepped surface 32. This increases the blocking area of ​​the outer inclined baffle 5, and its outer inclined surface has a greater slope, allowing water vapor particles to collide more fully on its outer inclined surface, causing more water vapor particles to settle and be discharged outside the wall at a faster speed. It is understood that in other embodiments, the top of the outer inclined baffle 5 may be connected to the upper edge of the connecting opening 34, or to a suitable position between the upper edge of the connecting opening 34 and the upper edge of the inner stepped surface 32.

[0050] In this embodiment, the ventilation device 20 also includes an inner inclined baffle 4. The bottom of the inner inclined baffle 4 is configured to connect to the wall surface of the wall vent 1 and is located inside the outer inclined baffle 5. The top of the inner inclined baffle 4 is connected to the inner stepped surface 32 and is set at the bottom of the connecting opening 34. Both sides of the inner inclined baffle 4 extend laterally upwards from the corresponding sides of the outer inclined baffle 5. The outer inclined surface of the inner inclined baffle 4 is in contact with the inner stepped surfaces 32 on the left and right sides of the connecting opening 34. After water vapor particles collide and settle on the inner stepped surfaces 32 on the left and right sides of the connecting opening 34, they are quickly discharged outside the wall along the outer inclined surface of the inner inclined baffle 4, preventing moisture from lingering on the bottom surface of the stepped air duct.

[0051] Furthermore, both sides of the inner inclined baffle 4 are connected to the corresponding inner surfaces of the stepped air duct, and the inner stepped surfaces 32 that cover the left and right sides of the connecting opening 34 laterally guide the water vapor particles flowing down from the inner stepped surfaces 32 to be discharged outside the wall by the outer inclined surfaces of the inner inclined baffle 4.

[0052] Furthermore, the bottom of the inner inclined baffle 4 is configured to connect to the bottom of the wall surface of the wall vent 1, and the top of the inner inclined baffle 4 is connected to the lower edge of the connecting opening 34, thereby avoiding obstruction of the connecting opening 34 and keeping the airflow of the connecting opening 34 unobstructed.

[0053] Furthermore, the bottom of the outer inclined baffle 5 is also configured to connect the bottom of the rainproof louver 6 and the bottom of the inner inclined baffle 4, forming a stable connection and improving the structural stability of the inclined inner inclined baffle 4 and the outer inclined baffle 5.

[0054] In this embodiment, the wall vent 1 is a square hole, the rainproof louver 6 is correspondingly square, the outer inclined baffle 5 is a square plate or sheet, and the pipe structure 30 is also cuboid, with its inner stepped surface 32 and connecting opening 34 both being square. The width w1 of the outer inclined baffle 5 is greater than the width w2 of the connecting opening 34, which better blocks water vapor particles in the airflow in the width direction, allowing the airflow to directly face the inner stepped surfaces 32 on both sides of the connecting opening 34 after being split from the left and right sides, preventing water vapor from directly entering the connecting opening 34 from the left and right sides of the outer inclined baffle 5. The inner inclined baffle 4 is also a square plate or sheet, with its width w3 equal to the width w4 of the inner stepped surface 32, and connects to the left and right sides of the stepped air duct. It should be noted that in other embodiments, the wall vent 1 can be a round hole, while the rainproof louver 6 and pipe structure 30 are both circular, and the inner inclined baffle 4 and outer inclined baffle 5 are correspondingly adapted accordingly.

[0055] In this embodiment, the duct structure 30 includes an air vent cover 2 and an internal air duct 3. The air vent cover 2 has an open end and a closed end. The open end is configured to connect to the inner side of the wall vent 1, and the closed end has a connecting hole. One end of the internal air duct 3 connects to the connecting hole. The inner stepped surface 32 is the inner surface of the closed end, and the connecting opening 34 is formed at one end of the connecting hole. When some water vapor particles enter with the airflow from the space between the left and right sides of the outer inclined baffle 5 and the inner side of the air vent cover 2, the airflow moves within the space formed between the inner side of the air vent cover 2, the inner stepped surface 32, and the back of the outer inclined baffle 5. The water vapor particles collide, settle, and are discharged outside the wall, allowing drier air to flow into the connecting opening 34. The duct structure 30 is formed by connecting the air vent cover 2 and the internal air duct 3, adopting a split structure, which reduces processing difficulty and saves manufacturing costs. It is understood that in other embodiments, the duct structure 30 is a one-piece molded structure, which facilitates simplified assembly.

[0056] Furthermore, the open end of the vent cover 2 is configured to connect to the inner surface of the wall 10, while covering the inner side of the wall vent 1, thereby communicating with the wall vent 1. It is understood that in other embodiments, the open end of the vent cover 2 can be inserted into the inner side of the wall vent 1 to achieve communication between the two.

[0057] Please see Figure 4 Combined Figures 1 to 3 , Figure 4 A flowchart illustrating an installation method for a ventilation device according to an embodiment of this application is shown.

The inner stepped surface 32 faces the wall vent 1.

[0059] S110. The top of the outer inclined baffle 5 is connected to the inner stepped surface 32 above the connecting opening 34, and the bottom of the outer inclined baffle 5 is connected to the wall surface of the wall vent 1, so that the outer inclined baffle 5 blocks the connecting opening 34. Both sides of the outer inclined baffle 5 are spaced apart from the corresponding inner surfaces of the stepped air duct.

[0060] S120. Install the rainproof louver 6 on the wall vent 1, and place it outside the outer inclined baffle 5.

[0061] This installation method involves sequentially installing the pipe structure 30, the outer inclined baffle 5, and the rainproof louver 6 from the inside out.

The connection method is a mechanical connection, and weather-resistant sealant is applied around the connection point.

[0063] In this embodiment, before step S110, the installation method further includes the following steps:

[0064] S102. Connect the top of the inner inclined baffle 4 to the inner stepped surface 32, so that the top of the inner inclined baffle 4 corresponds to the bottom of the connecting port 34, and connect the bottom of the inner inclined baffle 4 to the wall surface of the wall vent 1. Both sides of the inner inclined baffle 4 extend laterally to the corresponding sides of the outer inclined baffle 5.

[0065] Furthermore, in step S102, the bottom of the inner inclined baffle 4 is connected to the bottom of the wall surface of the wall vent 1, and the top of the inner inclined baffle 4 is connected to the lower edge of the connecting opening 34, and weather-resistant sealant is applied to the connection point. Both sides of the inner inclined baffle 4 are connected to the corresponding inner surfaces of the stepped air duct.

[0066] Furthermore, in step S110, the bottom of the outer inclined baffle 5 is connected to the bottom of the wall surface of the wall vent 1, the bottom of the rainproof louver 6, and the bottom of the inner inclined baffle 4, and the top of the outer inclined baffle 5 is connected to the upper edge of the inner stepped surface 32, and weather-resistant sealant is applied to the connection point.

[0067] Furthermore, in step S120, the rainproof louvers 66 are installed in the wall ventilation holes 1 and are flush with the exterior facade, and the connection method is mechanical connection.

[0068] Please see Figure 5 Combined Figures 1 to 3 , Figure 5 A flowchart illustrating the installation method of a ventilation device according to another embodiment of this application is shown. Compared to the installation method of the ventilation device in the above embodiments, the installation method of the ventilation device in this embodiment is carried out on the basis of a pipe structure 30 connected to the inner side of the wall vent 1, that is, the step of installing the pipe structure 30 is omitted. The pipe structure 30 may be an existing structure in the building 100, which has a stepped air duct inside and has an inner stepped surface 32 and a connecting opening 34 located on the inner stepped surface 32, with the inner stepped surface 32 facing the wall vent 1.

The specific content can be referred to the description of the above embodiments, and will not be repeated here.
