[0025] The utility model will be further described in conjunction with the drawings and specific embodiments.

[0026] Reference Figures 1 to 5As shown, the electrically adjustable air valve 100 provided by the embodiment includes a fixed pipe 10, an annular gear 20, a motor 40, a driving gear 41 and a plurality of valve pieces 30. The fixed pipe 10 has a ventilation port 101, and the center of the ventilation port 101 is provided with a hinged seat 11. In the embodiment, the hinged seat 11 is connected to the end wall of the fixed pipe 10 through four connecting supports 12, and the four connecting supports 12 divide the ventilation port 101 into four fan-shaped windows. The valve pieces 30 are fan-shaped valve pieces, and the number is four. The four valve pieces 30 are distributed at the ventilation port 101 of the fixed pipe 10, that is, one valve piece 30 is assembled in each fan-shaped window. The inner side of the valve piece 30 is rotatably assembled on the hinged seat 11, and the outer side is rotatably assembled on the end wall of the fixed pipe 10 and is provided with a driven gear 33. The annular gear 20 is rotatably sleeved on the outer periphery of the fixed pipe 10. The annular gear 20 has an annular tooth 21 arranged at the end thereof and a side tooth 22 arranged at the side end thereof. The annular tooth 21 of the annular gear 20 is engaged with the driven gears 33 on the four valve pieces 30 at the same time. The output shaft of the motor 40 is connected to the driving gear 41, and the driving gear 41 is engaged with the side tooth 22 of the annular gear 20. The motor 40 drives the annular gear 20 to rotate through the driving gear 41, and in turn drives the four valve pieces 30 to rotate synchronously, so as to adjust the flow area of the ventilation port 101 of the fixed pipe 10. That is, when the four valve pieces 30 rotate, the blades will swing. When the four valve pieces 30 are swung to be parallel to the ventilation port 101 of the fixed pipe 10, each valve piece 30 will completely cover the corresponding fan-shaped window. At this time, the flow area of the ventilation port 101 of the fixed pipe 10 is zero, that is, it is in the closed state as shown in Figure 4 When the motor 40 drives the valve pieces 30 to rotate from the closed state, the ventilation port 101 is gradually opened, that is, the flow area of the ventilation port 101 gradually increases, until the valve pieces 30 are rotated to be perpendicular to the ventilation port 101, and the opening is maximum, as shown in Figure 5

[0027] The motor 40 synchronously drives the plurality of valve pieces 30 to rotate, so as to adjust the flow area of the ventilation port 101 of the fixed pipe 10, and realizes the effect of electrically adjusting. Moreover, the motor 40 is used to synchronously drive the plurality of valve pieces 30 to rotate, so as to accurately control the flow of the air valve. At the same time, the valve pieces 30 are configured to be only rotating structure (that is, without other lifting or translation actions), which is more stable and is not easy to cause action jamming and other problems.

[0028] ​Specifically, in the embodiment, the hinge seat 11 is connected with the end wall of the fixed pipe 10 through four connecting supports 12, and the four connecting supports 12 divide the ventilation port 101 into four fan-shaped windows, and the valve piece 30 is a fan-shaped valve piece to achieve adaptation, which is one of the preferred embodiments. Of course, in other embodiments, the number of connecting supports 12 can also be three or more than four, and by changing the shape of the connecting support 12, that is, a plurality of connecting supports 12 can also divide the ventilation port 101 into a plurality of windows of other shapes, such as square, triangle, etc., and the number and shape of the valve piece 30 can also be adjusted accordingly.

[0029] Specifically, the valve piece 30 includes a connecting shaft 31 and a shielding piece (i.e. blade) connected to the opposite sides of the connecting shaft 31, the hinge seat 11 is provided with a mounting groove 111, the end wall of the fixed pipe 10 is provided with a mounting notch 13, the inner end of the connecting shaft 31 of the valve piece 30 is rotatably assembled in the mounting groove 111 of the hinge seat 11, and the outer end is rotatably assembled in the mounting notch 13 on the end wall of the fixed pipe 10 and connected to the driven gear 33, and the driven gear 33 is located on the outer side of the end wall of the fixed pipe 10. In this way, the rotatable arrangement of the valve piece 30 is achieved; the installation of the mounting groove 111 and the mounting notch 13 makes it easier to quickly install the valve piece 30; after the valve piece 30 is installed, it can be fixed by other structures, such as the abutting fixing by the first connecting pipe 50 in the embodiment.

[0030] Further, the inner end of the connecting shaft 31 of the valve piece 30 is also radially protruding to form a limiting portion 32, the mounting groove 111 is a T-shaped groove, and the limiting portion 32 is limited in the mounting groove 111. In this way, during installation, as long as the inner end of the connecting shaft 31 of the valve piece 30 is aligned with the T-shaped mounting groove 111 and put in, the precise installation and the inside and outside direction limiting of the valve piece 30 can be achieved, further ensuring that the valve piece 30 will not be offset.

[0031] The circumferential side of the fixed pipe 10 is also provided with a mounting bottom shell 14, and the motor 40 is fixedly arranged in the mounting bottom shell 14, so that the fixed pipe 10, the motor 40 and the valve piece 30 are fixedly installed. The side end of the ring gear 20 is provided with a radially outwardly extending support plate 23, and the outer side end of the support plate 23 forms the side teeth 22; the side teeth 22 are engaged with the driving gear 41.

[0032] Meanwhile, the first connecting pipe 50 is sleeved on the outside of the fixed pipe 10 from one end of the ventilation port 101, and covers the ring gear 20, the motor 40, the driving gear 41 and the plurality of valve pieces 30, so that the ring gear 20, the motor 40, the driving gear 41 and the plurality of valve pieces 30 are limited and not exposed; for example, the first connecting pipe 50 abuts against the top of the hinged seat 11 and the mounting gap 13, so as to limit the valve pieces 30 and the like, and realize stable installation. The first connecting pipe 50 is used for external connection of a pipeline. The second connecting pipe 60 is connected to the end of the fixed pipe 10 away from the ventilation port 101, and is used for external connection of a pipeline at the other end. Of course, in other embodiments, the structure of the first connecting pipe 50 or the second connecting pipe 60 can not be additionally provided; when the first connecting pipe 50 is not used, the ring gear 20, the motor 40, the driving gear 41 and the plurality of valve pieces 30 can be covered by other fixing covers and the like.

[0033] As shown in Figure 6 The embodiment also provides a kind of air distribution box, with three air ports, wherein three air ports are provided with the electrically adjustable air valve 100 described above.

[0034] Although the utility model is specifically shown and introduced in combination with the preferred embodiment, it should be understood by those skilled in the art that various changes can be made in form and details without departing from the spirit and scope of the utility model defined in the appended claims, and all changes are within the protection scope of the utility model.
