[0018] Figure 3 This is a schematic diagram of the first shell structure in this embodiment;

[0019] Figure 4 This is a schematic diagram of the second shell structure in this embodiment;

[0020] The components include a smoke generator 1, a first housing 2, a circular hole 2a, a turntable 3, a through hole 3a, a flexible filter ring 3b, a drive motor 4, a second housing 5, a hole 5a, and a cylinder 5b. Detailed Implementation

[0021] like Figure 1-4 As shown, this embodiment includes a smoke generator 1, a first housing 2, a turntable 3, a drive motor 4, and a second housing 5.

[0022] The first housing 2 has an inlet and an outlet channel, with the inlet end of the first housing 2 connected to the output end of the smoke generator 1. In this embodiment, the first housing 2 is a cubic box shape, with one face shaped like a frustum, and the end of the frustum connected to the output end of the smoke generator 1. A circular hole 2a is provided on the face of the first housing 2 opposite to the inlet.

[0023] The turntable 3 is a disc with a diameter larger than that of the circular hole 2a. The turntable 3 and the circular hole 2a are coaxial, and one side of the turntable 3 abuts against the side of the circular hole 2a. A through hole 3a is provided on the turntable 3, so that the smoke entering the first housing 2 can only exit through the through hole 3a. Specifically, in this embodiment, a flexible filter ring 3b with a diameter larger than that of the circular hole 2a is also provided at the position of the turntable 3 corresponding to the position of the circular hole 2a. The flexible filter ring 3b serves a sealing function to prevent smoke from leaking out from the gap between the turntable 3 and the first housing 2, and at the same time, it can reduce the contact area between the turntable 3 and the first housing 2, thereby reducing the frictional resistance of the turntable 3 rotation.

[0024] The second housing 5 has a channel with one inlet and multiple outlets. In this embodiment, the second housing 5 is also box-shaped, corresponding in shape to the first housing 2. One side of the second housing 5 has an opening, allowing the second housing 5 to fit snugly over the first housing 2, so that one bottom surface of the second housing 5 opposite the opening can abut against the other side of the turntable 3. Thus, the first housing 2 and the second housing 5 can clamp the turntable 3. The bottom surface of the second housing 5 also has several holes 5a as outlets for the second housing 5. The holes 5a are located within the rotation trajectory of the through holes 3a. The drive motor 4 drives the turntable 3 to rotate, causing the through holes 3a to connect to the holes 5a in sequence. Preferably, a cylinder 5b is also included, with one end of the cylinder 5b connected to the holes 5a and the other end of the cylinder 5b used for connecting external pipes.

[0025] The diameter of the through hole 3a is slightly larger than that of a single hole 5a. A flexible filter ring 3b with a diameter larger than that of the hole 5a is also provided on the surface of the through hole 3a corresponding to the hole 5a, which also serves to seal and reduce frictional resistance. In this embodiment, the flexible filter rings 3b are all made of fire-resistant flexible felt.

[0026] In this embodiment, the drive motor 4 is fixed on the outer surface of the second housing 5. A hole is opened on the fixed surface, through which the output shaft of the drive motor 4 is inserted into the second housing 5 and connected to the center of the turntable 3. The connection position between the hole and the drive motor 4 needs to be sealed.

[0027] Preferably, the second housing 5 in this embodiment has three outlet ends. Other numbers may be provided in other embodiments, depending on the specific circumstances.

[0028] The drive motor 4 drives the turntable 3 to rotate to a set position, allowing the smoke emitted by the smoke generator 1 to exit from the designated cylinder 5b. In practical applications, simply connect the three pipes to the three cylinders 5b respectively, and connect the other end of each pipe to a different room.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
