[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a precision electric air volume regulating air outlet, including a housing 1. The housing 1 is composed of two parts. One end of a part of the housing 1 is provided with a drive chamber 2. A drive motor 3 is fixedly installed in the drive chamber 2. The output end of the drive motor 3 is fixedly installed with a transmission screw 4. A transmission nut is threadedly connected to the rod body of the transmission screw 4. A valve plate 6 is fixedly installed on the side of the transmission nut. The other end of the valve plate 6 extends into the interior of the other part of the housing 1, and the valve plate 6 is slidably connected to the inner wall of the housing 1. Three groups of through holes 7 and current-limiting holes 8 are arranged at intervals on the surface of the valve plate 6. Three air ducts 9 are arranged on the surface of the housing 1. An electric control chamber 10 is arranged on the side of the housing 1. A spare battery box 11 and an electric control board 12 are arranged inside the electric control chamber 10.

[0020] By setting the valve plate 6 and arranging the drive motor 3 in the drive chamber 2, the drive motor 3 is used to drive the transmission screw 4 to rotate, and then the valve plate 6 is driven to move left and right through the transmission nut, which is convenient for later regulation of the supply / return air. And by setting the current-limiting holes 8, non-full-closed valve plate 6 air volume regulation is adopted. While adjusting the end air volume, the problem of whistling caused by too small opening of the air valve is also avoided.

[0021] A connecting flange 13 or a plugging and sealing piece 14 is fixedly installed at the end of the air duct 9. In actual use, it can be connected according to needs. The unnecessary air outlets can be sealed with the plugging and sealing piece 14. (One of the air outlet connecting flange 13 and the plugging and sealing piece is selected. For the port that does not connect the pipe, the connecting flange 13 is not installed, and the plugging and sealing piece 14 is installed instead).

[0022] The valve plate 6 adopts an L-shaped fold angle. The inner wall of the housing 1 is provided with a limiting groove 15. The two sides of the valve plate 6 are respectively slidably connected to the two limiting grooves 15. The valve plate 6 slides in the limiting groove 15 to prevent the valve plate 6 from rotating with the transmission screw 4.

[0023] A low-power remote Bluetooth module is arranged inside the electric control board 12 for remote signal transmission of the air outlet. An external power cord 16 is arranged at the end of the electric control chamber 10. The external power cord 16 is electrically connected to the electric control board 12. The electric control board 12 is electrically connected to the spare battery box 11 and the drive motor 3.

[0024] By setting the low-power remote Bluetooth module on the electric control board 12, there is no need to arrange control lines separately, and the installation is more convenient. And by setting the battery box 11, for some places where external power cannot be accessed, the housing 1 provides energy for the regulation of the end air volume by installing the battery box 11.

[0025] A partition plate 17 is fixedly installed on the inner wall of the driving chamber 2. The partition plate 17 divides the driving chamber 2 into a stroke chamber 18 and an installation chamber 19. The driving motor 3 is arranged inside the installation chamber 19, and the transmission screw rod 4 is arranged inside the stroke chamber 18. An oil injection port 20 is arranged on the surface of the outer housing 1. The oil injection port 20 is communicated with the stroke chamber 18. Lubricating oil is injected into the forming chamber 19 through the oil injection port 20 to avoid wear during the transmission process.
