[0012] The following describes in detail embodiments of the present invention. Examples of the embodiments are illustrated in the accompanying drawings, wherein identical or similar reference numerals throughout denote identical or similar elements or elements having identical or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention, and are not to be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "upper surface," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplification of the present invention. They do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation, and are therefore not to be construed as limiting the present invention. In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "fixed" are to be understood broadly, for example, to mean fixedly connected, removably connected, or integrally connected; mechanically connected, electrically connected, or capable of mutual communication; directly connected, indirectly connected through an intermediary, or internally connected between two elements, or interactively connected between two elements. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0013] See also Figure 1-2 The utility model provides an embodiment: an air duct structure for a constant humidity machine, comprising an equipment box 1, an air inlet 2 and an air outlet 3 are opened on the side wall of the equipment box 1.
[0014] Two hollow panels 4 are fixedly mounted on the inner bottom of the equipment box 1, symmetrically arranged along the central axis of the equipment box 1. Two air ducts 5 are connected between the two hollow panels 4, and are arranged horizontally and side by side. A baffle 6 is slidably mounted within the hollow panel 4, which serves to block and seal the air duct 5. The baffle 6 has a through hole, and a connecting pipe 7 is installed within the through hole. An arcuate groove 8 is formed on the side wall of the hollow panel 4 away from the air duct 5. One end of the connecting pipe 7 passes through the arcuate groove 8 and is placed outside the hollow panel 4. The other end of the connecting pipe 7 is placed inside the hollow panel 4 and cooperates with the end of the air duct 5.
[0015] A fixed plate 9 is mounted between the ends of the two baffles 6 positioned outside the hollow plate 4. A drive mechanism is connected to the fixed plate 9, which is used to control the reciprocating sliding of the baffles 6 within the hollow plate 4. The drive mechanism includes a stepper motor 11, which is fixedly mounted on the inner wall of the equipment box 1. A screw rod 12 is coaxially mounted on the output shaft of the stepper motor 11. A threaded hole is formed on the surface of the fixed plate 9, and the screw rod 12 passes through the threaded hole and is threadedly connected to the fixed plate 9.
