[0020] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the present utility model with reference to the drawings in the present utility model.

[0021] Example 1, as shown in Figure 1-2 Figure 4, a multi-outlet gas uniform distribution device includes a sealed housing 1. The sealed housing 1 is a closed hollow cavity structure. A gas inlet interface 2 is fixedly connected to the lower side of the side surface of the sealed housing 1. One end of the gas inlet interface 2 is communicated with the hollow cavity of the sealed housing 1, and the other end of the gas inlet interface 2 is connected to an inlet pipe 4;

[0022] A plurality of gas outlet interfaces 3 are uniformly installed on the upper side of the side surface of the sealed housing 1 along the outer surface. One end of the gas outlet interface 3 is communicated with the hollow cavity of the sealed housing 1; the other end of the gas outlet interface 3 is connected to an outlet pipe 5.

[0023] Working principle:

[0024] During use, the gas source can be connected to the gas inlet interface 2 through the inlet pipe 4, and each gas outlet interface 3 can be connected to the corresponding use nodes through the outlet pipe 5. Thus, when the gas source outputs gas, the gas will first enter the hollow cavity of the sealed housing 1 through the gas inlet interface 2. Thus, through the buffering effect of the hollow cavity of the sealed housing 1, the turbulence and eddy current during the gas flow can be reduced, so that the gas can be evenly dispersed in the hollow cavity of the sealed housing 1. Then, the gas in the hollow cavity of the sealed housing 1 is evenly distributed to each use node through each gas outlet interface 3 uniformly distributed on the outer surface of the sealed housing 1. Thus, the uniform distribution effect of the gas from a single inlet to multiple outlets is effectively realized.

[0025] Example 2, as a further preferred solution of Example 1, an annular flow guiding convex block 6 is arranged in the middle of the inner cavity of the sealed housing 1. Upper bowl-shaped grooves 62 and lower bowl-shaped grooves 63 are respectively arranged on the upper surface and the lower surface of the annular flow guiding convex block 6. A gas channel 61 is opened in the middle of the annular flow guiding convex block 6;

[0026] The annular flow guiding convex block 6 divides the inner cavity of the sealed housing 1 into an upper cavity and a lower cavity. The upper cavity and the lower cavity are communicated with each other through the gas channel 61. The gas inlet interface 2 is communicated with the lower cavity, and the gas outlet interface 3 is communicated with the upper cavity.

[0027] By arranging the annular flow guiding convex block 6 to divide the inner cavity of the sealed housing 1 into an upper cavity and a lower cavity, the gas first enters the lower cavity through the gas inlet interface 2, and then the input gas can be buffered through the lower cavity, and then the gas flow rate can be effectively reduced to avoid the problem that the gas flows out directly along one or more gas outlet interfaces 3 due to too fast gas flow rate; then, through the gas channel 61 in the middle of the annular flow guiding convex block 6, the gas in the lower cavity overflows upward into the upper cavity; then the effect that the gas can be evenly dispersed in the inner cavity of the sealed housing 1 can be effectively guaranteed.

[0028] Embodiment 3, as a further preferred solution of Embodiment 1, a dispersion pipeline 7 is arranged below one end of the air inlet interface 2 located in the hollow cavity of the sealed housing 1. The dispersion pipeline 7 and the air inlet interface 2 are integrally structured and communicate with each other. The lower end of the dispersion pipeline 7 is fixedly connected to a dispersion box 8, and a plurality of micropores 9 are evenly formed on the side surface and the lower surface of the dispersion box 8.

[0029] Therefore, when the gas is output from the air inlet interface 2 into the hollow cavity of the sealed housing 1, it will first enter the dispersion box 8 through the dispersion pipeline 7, and then be dispersed into the inner cavity of the sealed housing 1 through the multiple micropores 9 on the side surface and the lower surface of the dispersion box 8. Thus, the dispersion box 8 can effectively reduce the flow rate of the gas, and at the same time, by arranging a plurality of micropores 9, the gas can be evenly dispersed and input into the hollow cavity of the sealed housing 1. In addition, by arranging the dispersion box 8 downward, the gas flows out through the micropores 9 towards the lower part of the cavity of the sealed housing 1, and then the gas can be further effectively buffered, thereby further ensuring the effect of the gas being evenly dispersed in the inner cavity of the sealed housing 1.

[0030] Embodiment 4, as a further preferred solution of Embodiment 1, a porous medium layer 10 is installed in the upper bowl-shaped groove 62. In this embodiment, the porous medium layer 10 can adopt a porous ceramic structure, so as to achieve the uniform dispersion of the gas through the micro-channels inside the porous medium layer 10.

[0031] Embodiment 5, as a further preferred solution of Embodiment 1, an air inlet pipe valve 21 is installed on the air inlet interface 2, and an air outlet pipe valve 31 is installed on each air outlet interface 3. Therefore, when it is necessary to control the number of air outlet interfaces 3 in use, the corresponding number of air outlet pipe valves 31 can be opened as required.

[0032] Embodiment 6, as a further preferred solution of Embodiment 1, the sealed housing 1 includes a lower support 11, an intermediate housing 12 and an upper cover plate 13. The intermediate housing 12 is a hollow housing structure that is vertically penetrated. The lower surface of the intermediate housing 12 is installed on the upper surface of the lower support 11, and the upper cover plate 13 covers the upper surface of the intermediate housing 12. Screws 14 are vertically installed at the four corner positions of the lower support 11, and the upper ends of the screws 14 pass through the upper cover plate 13 and are threadedly connected to locking nuts 15. In this embodiment, the upper surface and the lower surface of the intermediate housing 12 are hermetically connected to the upper cover plate 13 and the lower support 11 respectively through sealing rings.

[0033] Therefore, when maintenance is required for the components inside the sealed housing 1, the locking nut 15 can be directly removed, and then the lower support 11, the intermediate housing 12, and the upper cover plate 13 can be separated. Since the intermediate housing 12 is a hollow housing structure that is vertically through, the components inside the intermediate housing 12 can be directly maintained. And in this embodiment, the upper surface and the lower surface of the intermediate housing 12 are respectively sealed and connected to the upper cover plate 13 and the lower support 11 through sealing rings, so the sealing performance and safety of the sealed housing 1 during gas transportation can be effectively ensured.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
