[0018] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the utility model is further explained in detail below in combination with specific implementation manners and referring to the drawings. It should be explained that the embodiment of the utility model and the feature in the embodiment can be combined mutually in the case of not conflicting.

[0019] Some embodiments of the utility model are described below in combination with the drawings to provide a kind of adjust fresh air balance air valve.

[0020] Embodiment:

[0021] In combination Figs. 1-3The utility model provides a kind of adjusting fresh air balance damper shown, including main body mechanism and adjusting mechanism, main body includes valve body 110, connecting on the inner wall of valve body 110 sliding rod 130, slidingly connected on sliding rod 130 ventilating plate 150, ventilating opening 160 being opened in the middle part of ventilating plate 150, drive motor 170 being arranged in the central interior of ventilating plate 150, fixed piece 120 is installed on the outside of the both ends of valve body 110, fixed piece 120 is used to fix the position of valve body 110, spring 140 is sleeved on sliding rod 130, the inner end of spring 140 is fixedly connected with ventilating plate 150, adjusting mechanism includes connecting on the output of drive motor 170 rotating shaft 210, connecting on the top of rotating shaft 210 outer fan blade 220, rotating in the middle part of outer fan blade 220 balance plate 240, lap in the middle part of torsion spring plate 230 of balance plate 240, the inside of ventilating plate 150 is provided with the inner fan blade 221 corresponding with outer fan blade 220, torsion spring plate 230 and balance plate 240 are also provided on inner fan blade 221, the number of ventilating opening 160 is four, the number of blade of outer fan blade 220 and inner fan blade 221 is two, and outer fan blade 220 and inner fan blade 221 are perpendicular to each other.

[0022] Specifically, sliding rod 130 is slidably connected with ventilating plate 150, and spring 140 generates a pressure on ventilating plate 150, so that sudden wind impact is buffered by spring 140 in a sealed state, reducing damage to the structure, and also resisting the impact of foreign matter, further improving the practicability of the device, and the rotation angle of outer fan blade 220 and inner fan blade 221 can be limited by sliding rod 130 to avoid excessive rotation angle, which causes confusion between the ventilating openings 160 blocked by the two, thereby reducing the sealing effect, and even causing structural damage, improving the practicability of the device.
