[0019] The embodiments of the utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the utility model, and cannot be construed as a limitation to the utility model.

[0020] Embodiments of the utility model: As Figures 1 - 3As shown in the figure, a gas path switching device for a moisture exhaust pipe box includes a box body 1. An air inlet 2 is provided on one side wall of the box body 1. A first air outlet 3 is provided on the side wall of the box body 1 opposite to the air inlet 2. The height of the first air outlet 3 is lower than that of the air inlet 2. A second air outlet 4 is provided on the top plate of the box body 1. An inclined wall 6 and a lapping plate 7 are fixedly arranged in the box body 1. The lapping plate 7 is arranged above the air inlet 2. One end of the inclined wall 6 is located below the air inlet 2, and the other end of the inclined wall 6 is connected to the lower edge of the first air outlet 3. An electric flap mechanism is arranged in the box body 1. The electric flap mechanism has a first working position and a second working position. When in the first working position, the electric flap mechanism lapps with the lapping plate 7. When in the second working position, the electric flap mechanism lapps with the inclined wall 6.

[0021] For the convenience of description, the side wall provided with the air inlet 2 is called the front side wall, and the side wall provided with the first air outlet 3 is called the rear side wall. The air inlet 2 is located in the upper middle part of the front side wall. The air inlet 2 is a round hole and is connected to a ventilation pipe.

[0022] The first air outlet 3 is provided at the bottom of the rear side wall. The first air outlet 3 is a square hole, and an installation strip 14 with screw holes is arranged at its outer end, which is a flange-like structure for connecting one of the air ducts. The second air outlet 4 is provided on the top plate of the box body 1 and is close to the rear side wall. The second air outlet 4 is also a square hole, and an installation strip 14 with screw holes is also arranged at its outer end for connecting another air duct.

[0023] The lower end of the inclined wall 6 extends horizontally and then extends to the lower edge of the first air outlet 3. Both sides of the inclined wall 6 are fixedly connected to the other two side walls of the box body 1.

[0024] Furthermore, the electric flap mechanism is arranged close to the side wall with the first air outlet 3. The electric flap mechanism includes a flap 5, a swing arm 8, and an electric telescopic rod 9. One end of the flap 5 is hinged to the two side walls of the box body 1 through a hinge shaft 11. One end of the swing arm 8 is fixedly connected to the hinge shaft 11. The other end of the swing arm 8 is hinged to the telescopic end of the electric telescopic rod 9. The base of the electric telescopic rod 9 is hinged to the side wall of the box body 1 or the inclined wall 6.

[0025] In this embodiment, the base of the electric telescopic rod 9 is hinged to the outer side wall of the box body 1. One end of the hinge shaft 11 penetrates through the side wall of the box body 1 and extends out of the box body 1. The swing arm 8 is located outside the box body 1. One end of the swing arm 8 is fixedly connected to the end of the hinge shaft 11 extending out of the box body 1. The other end of the swing arm 8 is hinged to the telescopic end of the electric telescopic rod 9.

[0026] When the electric telescopic rod 9 extends or contracts, it drives the swing arm 8, and the swing arm 8 drives the hinge shaft 11 to rotate. When the hinge shaft 11 rotates, the flap 5 moves between the first working position and the second working position. It should be noted that the electric telescopic rod 9 and the swing arm 8 are only one of the preferred solutions for driving the rotation of the hinge shaft 11, and other technical solutions capable of driving the rotation of the hinge shaft 11 are also within the protection scope of the present utility model. For example, using a motor and a gear set to drive the hinge shaft 11, replacing the electric telescopic rod with an oil cylinder or a pneumatic cylinder, etc.

[0027] Furthermore, a maintenance door 10 is provided on the rear side wall, and the position of the maintenance door 10 is opposite to the electric flap mechanism. A horizontal transition plate 12 is provided between the hinge shaft 11 and the maintenance door 10, and both ends of the horizontal transition plate 12 are fixedly connected to the inner wall of the box body 1.

[0028] Setting the maintenance door 10 can clean the top surface of the flap 5 and the horizontal transition plate 12, and setting the horizontal transition plate 12 is used to block the gap between the hinge shaft 11 and the rear side wall.

[0029] Furthermore, a cleaning nozzle 13 is provided inside the box body 1 near the first air outlet 3. Since the impurities in the moisture exhaust steam need to be discharged from the first air outlet 3 through the inclined wall 6, adding the cleaning nozzle 13 here facilitates cleaning the lower end of the inclined wall 6.

[0030] The working principle of the present utility model: When it is necessary to send the moisture exhaust steam into the downstream equipment through the first air outlet 3, the electric telescopic rod 9 extends. Under the push of the electric telescopic rod 9, the swing arm 8 flips upward and drives the hinge shaft 11 to rotate, and the flap 5 on the hinge shaft 11 also flips upward. When the end of the flap 5 overlaps with the overlapping plate 7, the electric telescopic rod 9 stops working. At this time, the flap 5 is in the first working position, and a first exhaust air channel is formed between the air inlet 2 and the first air outlet 3. The inclined wall 6 serves as the bottom wall of the first exhaust air channel, the two inner walls of the box body 1 serve as the side walls of the first exhaust air channel, and the overlapping plate 7, the flap 5 and the horizontal transition plate 12 serve as the top wall of the first exhaust air channel. The moisture exhaust steam flows in the first exhaust air channel. During the process that the impurities mixed in the moisture exhaust steam flow from top to bottom, the impurities fall on the inclined wall 6 and then gather at the first air outlet 3, which greatly facilitates cleaning.

[0031] When it is necessary to send the moisture-exhausting water vapor into the downstream equipment through the second air exhaust port 4, the electric telescopic rod 9 contracts. Under the pulling of the electric telescopic rod 9, the swing arm 8 flips downward and drives the hinge shaft 11 to rotate. The flap 5 on the hinge shaft 11 also flips downward. When the end of the flap 5 abuts against the inclined wall 6, the electric telescopic rod 9 stops working. At this time, the flap 5 is in the second working position, and a second air exhaust channel is formed between the air inlet 2 and the second air exhaust port 4. At this time, a part of the inclined wall 6, the flap 5 and the horizontal transition plate 12 form the bottom wall of the second air exhaust channel. The two inner walls of the box body 1 serve as the side walls of the second air exhaust channel, and the overlapping plate 7 serves as the top wall of the second air exhaust channel. The moisture-exhausting water vapor flows in the second air exhaust channel. The impurities mixed in the moisture-exhausting water vapor converge in the first half of the flap 5 and the inclined wall 6 and converge on the surface of the inclined wall 6 along the inclined plane. When the flap 5 switches directions again, these impurities slide along the inclined wall 6 to the first air exhaust port 3 for cleaning. The moisture-exhausting water vapor is discharged from the second air exhaust port 4 along the second air exhaust channel.

[0032] The structure, features and function effects of the present utility model have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present utility model, but the present utility model is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present utility model, or modified into equivalent embodiments with equivalent changes, still within the spirit covered by the description and the drawings, shall fall within the protection scope of the present utility model.
