Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples, the present invention being described in further detail, this embodiment is only used for explaining the present invention, protection scope of the present invention is not constituted and limits。
As depicted in figs. 1 and 2, the present embodiment provides the exhaust muffling device of a kind of oxygenerator, including hush pipe 2, exhaustor 1 and follower, described hush pipe is closed cylindrical structure, the baffle plate 4 of the straight plate form of polylith it is provided with in described hush pipe 2, each described baffle plate 4 is different in size, laterally distributed in described hush pipe 2, one end of described baffle plate 4 is connected with bottom described hush pipe 2, one side of described baffle plate 4 is connected with the side of described hush pipe 2, described exhaustor 1 has two, it is connected to described hush pipe 2 two ends, wherein an exhaustor 1 is connected with switching valve, another root is connected with described follower。Described baffle plate 4 has 8, and its length is respectively less than the 1/2 of hush pipe cylinder side length, and described baffle plate spreads out in the upper bottom portion and lower bottom part that are separately fixed at hush pipe cylinder 2, and described upper bottom portion and lower bottom part are respectively symmetrically and are provided with 4 described baffle plates 4。The two ends of described hush pipe 2 are provided with pipeline connection port 3, are provided with reinforcement 5 outside described hush pipe cylinder 2。It is fixing that described reinforcement 5 adopts 3 ~ 5 bar shaped reinforcements to be distributed outside described hush pipe cylinder 2。Two described exhaustors 1 are connected with the pipeline connection port 3 at the two ends of described hush pipe 2 respectively。Described follower includes input pipe road junction 6 and exhaust funnel 7。Described exhaust funnel 7 is cylindric, and lower disc opening, upper disc is the closing disc with outlet tube road junction, is provided with a disc being covered with aperture venthole in the middle part of described exhaust funnel 7。Described hush pipe and follower all adopt PVC material to make。
