[0022] This utility model provides a mixed gas distribution device, including a housing 1, a central shaft 2, an inlet pipe 3, two outlet pipes 4, a connecting pipe 5, two rotating mechanisms, and a pushing assembly. Each of the rotating mechanisms includes a limiting shell 6, a sealing plate 7, a limiting block 8, and two limiting rods 9. The pushing assembly includes two pushing plates 10 and two fixing blocks 11. The aforementioned solution solves the problem in the prior art where the piston plate and rubber ring have limited range of motion, making it difficult to completely discharge the gas.

[0023] In this specific embodiment, the central shaft 2 is rotatably connected to the housing 1 and located inside the housing 1. Two rotating mechanisms are respectively disposed on both sides of the central shaft 2. The pushing assembly is disposed on the top of the housing 1. The two rotating mechanisms divide the housing 1 into two cavities 15. The limiting shell 6 is fixedly connected to the central shaft 2 and located on one side of the central shaft 2. A cavity 16 is provided on one side of the limiting shell 6. The sealing plate 7 is slidably connected to the limiting shell 6 and located on one side of the limiting shell 6. The limiting block 8 is fixedly connected to the sealing plate 7 and located on one side of the sealing plate 7. The limiting block 8 is disposed inside the cavity 16. One end of each of the two limiting rods 9 is fixedly connected to the limiting shell 6. The two limiting rods 9 are slidably connected to the sealing plate 7 and located inside the cavity 16. A motor 12 is provided above the housing 1, and the output end of the motor 12 is fixedly connected to the central shaft 2. A first cylinder 13 is provided inside the limiting shell 6, and the output end of the first cylinder 13 is fixedly connected to the corresponding sealing plate 7. Gas is injected into the corresponding cavity 15. After the gas ratio is completed, the first cylinder 13 pulls the sealing plate 7, causing the sealing plate 7 to move along the limiting rods 9. The sealing plate 7 moves into the cavity 16, and the motor 12 drives the central shaft 2 to rotate, causing the limiting shell 6 and the sealing plate 7 to rotate accordingly, thus mixing the gas.

[0024] Two push plates 10 are slidably connected to the housing 1 and are respectively disposed on both sides of the central shaft 2. The push plates 10 are adapted to the central shaft 2, the sealing plate 7 and the limiting shell 6. A first cylinder 14 is disposed above the housing 1. The output end of the first cylinder 14 is fixedly connected to the corresponding push plate 10. When the gas is mixed, the first cylinder 14 pushes the push plate 10 to push the gas out of the housing 1.

[0025] Secondly, the two fixing blocks 11 are fixedly connected to the housing 1 and located between the two push plates 10. The fixing blocks 11 are adapted to the central shaft 2 and the two push plates 10. The fixing blocks 11 are locked above the corresponding limiting shell 6, which improves the accuracy of the gas introduction ratio.

[0026] Secondly, the two air inlet pipes 3 are fixedly connected to the housing 1 and are respectively arranged on both sides of the housing 1. The two air inlet pipes 3 are respectively connected to the corresponding cavities 16, and gas is added through the air inlet pipes 3 to the interior of different cavities 15.

[0027] In addition, one end of each of the two air outlet pipes 4 is fixedly connected to the housing 1, and the sections of the two air outlet pipes 4 are fixedly connected to the connecting pipe 5. The air outlet pipes 4 are connected to the corresponding cavities 16. After the gas is mixed, the push plate 10 pushes the gas and discharges the gas through the air outlet pipes 4.

[0028] When using this utility model, gas is added through the air inlet pipe 3 and injected into different cavities 15. After the gas ratio is completed, the first cylinder 13 pulls the sealing plate 7, causing the sealing plate 7 to move along the limiting rod 9. The sealing plate 7 moves into the cavity 16. The motor 12 drives the central shaft 2 to rotate, causing the limiting shell 6 and the sealing plate 7 to rotate accordingly, mixing the gas. The first cylinder 14 pushes the push plate 10 to discharge the gas through the air outlet pipe 4.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
