Wherein, install but manually operation's flow control assembly 3 in the air inlet of air current passageway, change the flow velocity of flow of gas in each air current passageway through flow control assembly 3, reduce the air inlet to the air current passageway of nearer position, improve the air inlet to the air current passageway of farther position for the velocity difference between the long-range and near positions is balanced.
In this embodiment, the airflow channel includes an edge channel 12 and a central channel 13, one ends of the edge channel 12 and the central channel 13 are connected to the same air inlet 11 formed on the wind discharge pipe body 1, the other end of the edge channel 12 is led to one side, close to the inner wall, in the converging air cavity, and the other end of the central channel 13 is led to the central position in the converging air cavity.
When the container is filled with gas, the gas usually stays in the center of the container, and gradually spreads to the edge of the container along with the continuous filling of the gas, so that the time difference of filling the gas in the container is caused, and the gas is unevenly distributed if the gas is directly released. Therefore, the edge channel 12 and the center channel 13 are arranged to respectively charge the edge and the center of the converging air cavity, so that the air at each position in the air cavity is uniformly charged.
Preferably, a first partition plate 21 and a second partition plate 22 are arranged in the converging air cavity, one end of the first partition plate 21 is arranged at the air inlet 11, the first partition plate 21 and the inner wall of the air flow channel are surrounded to form an edge channel 12, and the second partition plate 22 and the first partition plate 21 are surrounded to form a central channel 13.
The first partition plate 21 is arranged at the air inlet 11 to divide the air inlet 11 evenly, the edge channel 12 formed by the first partition plate 21 and the converging air cavity guides the air flow along the edge of the cavity, so that the air flow can enter the edge area of the cavity at the first time, and the second partition plate 22 forms the central channel 13 by using the first partition plate 21 to guide the air flow to the central area, so that the two air flow channels aiming at different areas are arranged.
Preferably, the flow regulating assembly 3 includes a deflector 31 and a rotating shaft 32, the rotating shaft 32 is rotatably disposed on the wind bank pipe body 1 at one end of the first partition 21 near the air inlet 11, and the deflector 31 is disposed on the rotating shaft 32 to swing along with the rotation of the rotating shaft. The baffle 31 is just at the air inlet 11, and the baffle 31 is deflected to the side of the edge channel 12 or the central channel 13 by rotating the rotating handle of the rotating shaft 32 extending out of the tube body.
When the baffle 31 deflects toward the side of the central passage 13, the air inlet of the central passage 13 becomes smaller and the air inlet of the edge passage 12 becomes larger, so that more air flows introduced from the air inlet 11 enter the edge passage 12, and the increased air flow rate also strengthens the flow velocity because the inner diameter of the edge passage 12 is unchanged, thereby solving the problem of slow air flow filling in the edge area. In addition, the angle of the baffle 31 can be precisely adjusted so that the intake air amount and the filling rate in the cavity are balanced.

The long side of the adjusting plate 42 is slightly shorter than the bottom surface of the adjusting slot 4, and the width of the short side is adapted to the slot wall, so that the adjusting plate 42 can slide linearly by utilizing the space of the long side. When the movable air hole 43 and the fixed air hole 41 slide to one end, the movable air hole 43 and the fixed air hole 41 are completely overlapped, and for the maximum release of the air flow, when the movable air hole 43 and the fixed air hole 41 slide to the other end, the release outlet of the air flow is closed, so that the air flow release amount of each adjusting air groove 4 can be controlled through the adjusting plate 42.
Wherein, the one end rotation of regulating plate 42 is connected with the bolt that stretches out outside regulating air tank 4, has installed the fixed plate on regulating air tank 4, still is fixed with the nut on the fixed plate, and the bolt passes the fixed plate and is connected with the nut, makes the operating personnel remove the position of regulating plate 42 through rotating the bolt to can make regulating plate 42 fix in the position at this time and keep the degree of opening and shutting of movable air vent 43 and fixed air vent 41.
Example 2
