[0027] The utility model embodiment provides a straight blowing air duct system, as shown in Figures 2-5 The utility model discloses a straight blowing air duct system, as shown in The utility model discloses a straight blowing air duct system, as shown in

[0028] Embodiment one, as shown in Figure 3As shown, the cross-section of the air guide curve duct 4 includes line 1 (41), line 2 (42), line 3 (43), line 44 (44), and line 5 (45). Line 1 (41) is located to the left of the air outlet of the volute 1. Line 1 (41) is an arc that bulges to the right, concentrating and guiding the airflow to the right. Line 5 (45) is located to the right of the air outlet of the volute 1. Line 5 (45) is an arc that bulges to the left. Line 2 (42) is located outside line 5 (45). Line 2 (42) has an angle of 26° with the horizontal line. The bulge of line 5 (45) further enhances this effect. The wind direction is guided again by line 2 42. Line 3 43 and line 44 are outside line 2 42. The angle between line 3 43 and the vertical line is 11.3° (the angle can be in the range of 11°-12°). The angle between line 2 42 and line 3 43 is 127°. Line 44 is perpendicular to the horizontal line. The wind direction is guided three times and finally discharged in a straight line. The angles are precisely calculated to guide the incoming wind evenly to the wind guide curve 4, avoiding the formation of vortices and turbulence at the bend.

[0029] Example 2, as Figure 4 and Figure 6 As shown, the airflow duct 4 also includes a rectification mechanism 5. This rectification device consists of multiple layers of parallel metal mesh, with the mesh size of each layer gradually decreasing. When air passes through these metal meshes, it further eliminates turbulence and irregular airflow, allowing the air to flow more smoothly within the duct. The metal mesh is made of corrosion-resistant nickel-chromium alloy, ensuring that the rectification effect will not be affected by oxidation or corrosion during long-term use.

[0030] In the above embodiments, the metal mesh is made of corrosion-resistant nickel-chromium alloy material to ensure that the rectification effect will not be affected by oxidation or corrosion during long-term use.

[0031] The opening end of the air guide curve duct 4 also includes an air outlet mechanism 7. The air outlet mechanism 7 includes a connection port and an adjustable nozzle 8. The shape of the connection port matches the cross-sectional shape of the air guide curve duct 4 to ensure smooth airflow. The nozzle 8 can be adjusted by rotation or sliding to change the airflow range. The adjustable nozzle 8 in the air outlet mechanism 7 can adjust the airflow range according to actual needs, increasing the flexibility and applicability of the duct system. Example 3, as... Figure 6 As shown, the air outlet mechanism 7 includes a connection port and an adjustable nozzle 8. The connection port is a square-to-round pipe. The nozzle 8 adjusts the air outlet range by rotating between several fan blades. For example, if the innermost fan blade is fixed, the other fan blades rotate in sequence and are connected, opening and closing like a fan to adjust the outlet size.

[0032] Installation process: preferably, the air guide curve air duct 4 is integrally formed with the volute 1, and the rectifier is installed inside the air guide curve air duct 4 near the air inlet, and is also fixed by bolts or welding, to ensure that the multiple layers of metal mesh of the rectifier are horizontal and parallel. Finally, the air outlet device is installed at the other end of the air guide curve air duct 4, and the air nozzle 8 is adjusted to the required angle and range by rotating or sliding, and is fixed by a locking device.

[0033] Working principle: when the straight blowing air duct system is used, the motor 2 drives the fan to rotate, and the air enters the air guide curve air duct 4 from the air outlet of the volute 1. In the air guide curve air duct 4, the air passes through the multiple layers of metal mesh of the rectifier, further eliminating turbulence and irregular airflow. Finally, the air is blown out from the air outlet of the air guide curve air duct 4, and the straight line air adjusted by the adjustable air nozzle 8 can accurately act on the target object, realizing the functions of air cooling, drying, etc.

[0034] In summary, the straight blowing air duct system extends the air guide curve air duct 4 at the air outlet of the original volute 1, and the designed air guide curve air duct 4 realizes straight line discharge through three times of air guiding, and the curved design avoids the formation of vortex and turbulence at the inlet, and changes the limitation that the air outlet of the traditional volute 1 is inclined and needs to be equipped with a wind pipe to guide the direction of the air.

[0035] 2、The straight blowing air duct system, the air guide curve air duct 4 adopts a straight cylinder-shaped air duct body and a smooth inner wall material, which reduces the friction and energy loss of the air and the air duct, so that the air can flow more stably in the air duct, thereby improving the conveying efficiency of the air.

[0036] 3、The straight blowing air duct system, the multiple layers of metal mesh in the rectifier mechanism 5 further eliminate turbulence, ensure the straight linearity and stability of the air in the air duct, and make the blown air be high-quality straight line air, which meets the application scenarios with high requirements for straight line air.
