[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Referring to the accompanying Figures 1 - 3 to the drawings, as Figure 1As shown in the figure, a gas premixing device for a constant-volume combustion bomb according to an embodiment of the present utility model includes a tank body 1. One side of the tank body 1 is communicatively connected with a primary mixing tank 2. A connecting rod 3 is fixedly installed on the inner wall of the primary mixing tank 2. One end of the connecting rod 3 is fixedly installed with a gas dispersing member 4. An air delivery pipe 5 is fixedly installed inside the gas dispersing member 4. A spiral blade 6 is fixedly installed inside the gas dispersing member 4. A support frame 21 is fixedly installed on the inner wall of the air delivery pipe 5, as Figure 2 shown. A sliding rod 7 is slidably connected inside the support frame 21. One end of the sliding rod 7 is fixedly installed with a sealing plug 9. A spring 8 is arranged on one side of the sealing plug 9. The spring 8 is fixedly installed on one side of the support frame 21, as Figure 3 shown. One side of the primary mixing tank 2 is communicatively connected with a first air inlet pipe 10. The air delivery pipe 5 and the first air inlet pipe 10 are communicatively connected. One side of the primary mixing tank 2 is communicatively connected with a second air inlet pipe 11. A first valve 12 is rotatably connected inside the second air inlet pipe 11. A rotating handle 13 is fixedly installed on the top of the first valve 12. The rotating handle 13 is rotatably connected inside the second air inlet pipe 11, as Figure 1 shown. A shaft rod 14 is rotatably connected inside the tank body 1. A first mixing member 15 is fixedly installed on the outer side of the shaft rod 14. A second mixing member 16 is fixedly installed on the outer side of the shaft rod 14. A motor 17 is fixedly installed on one side of the tank body 1. The shaft rod 14 is fixedly installed at the output end of the motor 17. An air outlet pipe 18 is communicatively connected to the top of the tank body 1. A second valve 19 is rotatably connected inside the air outlet pipe 18. A connecting pipe 20 is fixedly installed on one side of the air outlet pipe 18.

[0018] It should be noted that when premixing the gas in the constant volume combustion bomb, different gases are respectively transported into the inner side of the primary mixing box 2 through the first inlet pipes 10 and the second inlet pipes 11 on both sides. When transporting gas through the second inlet pipe 11, the first valve 12 is rotated by turning the handle 13, so that the second inlet pipe 11 communicates with the primary mixing box 2. At this time, the gas can enter the primary mixing box 2. The gas entering will contact the gas dispersing member 4, and under the limitation of the gas dispersing member 4, the gas is dispersed towards the periphery of the gas dispersing member 4, and finally converges at the channel at the center position of the primary mixing box 2. When transporting gas through the first inlet pipes 10 on both sides, the first inlet pipe 10 can be connected to the gas input pipe. After the gas enters the gas transmission pipe 5 through the first inlet pipe 10, the gas will push the sealing plug 9 to slide, so that the gas is transported to the spiral blade 6 through the side of the sealing plug 9. When the gas in the gas transmission pipes 5 on both sides flows out, it will be transported to one side through the spiral blade 6. When the two gases are transported in the spiral blade 6, they will gradually mix together. After flowing out from the spiral blade 6, they will flow through the channel at the center position of the primary mixing box 2 at the same time, so as to intersect with the gas flowing in from the second inlet pipe 11 and mix together after passing through the primary mixing box 2, thereby realizing the convenient mixing of different gases. At the same time, when the mixed gas enters the tank body 1, the motor 17 is started to drive the shaft rod 14 to rotate, and the mixed gas is stirred by a plurality of first mixing members 15 and second mixing members 16, further ensuring the sufficiency of gas mixing and being able to avoid the sedimentation and stratification phenomenon of the mixed gas stored in the tank body 1. When it is necessary to use the mixed gas in the tank body 1, by connecting the adapter pipe 20 to the constant volume combustion bomb device and rotating the second valve 19, the gas in the tank body 1 can be introduced. In actual use, the first inlet pipe 10 and the second inlet pipe 11 can be selected for use according to the quantity of the mixed gas, so as to meet different use requirements and have a lower cost and be conducive to popularization.
