The existing static pressure box has problems such as the airflow at the upper and lower air outlets cannot be effectively controlled according to the needs, and the noise is high. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] See Figures 1 to 5 This embodiment provides a static pressure box with an air regulating mechanism, including a box body 1, a fan 2, and an air regulating mechanism 4. The front of the box body 1 is provided with a first air outlet 11 and a second air outlet 10 separated by a partition. The air outlets of the second air outlet 10 and the first air outlet 11 are vertically distributed and parallel to each other. A ventilation duct 13 communicating with the first air outlet 11 and the second air outlet 10 is provided inside the box body 1. The fan 2 is installed inside the box body 1, and an arc-shaped air guide plate 12 is provided on the outer side of the fan blades. The air deflector 12 is aligned with the ventilation duct 13. An adjusting flap 5 is rotatably installed in the ventilation duct 13 relative to the air inlet of the first air outlet 11. The air regulating mechanism 4 is installed on the housing 1 and is connected to the adjusting flap 5 to control the rotation of the adjusting flap 5, thereby regulating the air volume flowing to the first air outlet 11 and the second air outlet 10. The adjusting flap 5 is rotatably installed in the ventilation duct 13 via a rotating shaft. The arc-shaped air guide plate 12 enables the air field generated by the fan to be stably delivered to the ventilation duct to achieve smooth air output.

[0023] In this embodiment, refer to Figure 2 and Figure 3 The fan 2 is eccentrically positioned inside the housing 1. When the fan 2 is working, a vortex wind field is formed inside the housing 1, which helps to reduce wind loss.

[0024] In this embodiment, refer to Figure 3 and Figure 4 Both the first air outlet 11 and the second air outlet 10 are equipped with flow stabilizers 3 at their air inlets. The flow stabilizers 3 have the same air outlet direction as the ventilation duct 13. The lower end of the flow stabilizer 3 at the first air outlet 11 is inclined. An adjusting flap 5 is obliquely positioned below the flow stabilizer 3 at the first air outlet 11. After the adjusting flap 5 is flipped upwards at a certain angle, it can completely block the flow stabilizer 3 at the first air outlet 11 to close the air inlet of the first air outlet 11. During the upward flipping of the adjusting flap 5, the airflow to the first air outlet 11 is reduced. The flow stabilizers 3 play a certain role in stabilizing the airflow, making the air output from the first air outlet 11 and the second air outlet 10 more uniform and stable.

[0025] In this embodiment, refer to Figure 3 and Figure 4 The partition has a rounded transition structure at one end near the ventilation duct 13, which reduces airflow impact when the airflow in the ventilation duct 13 flows to the air outlet, further reducing air loss and noise.

[0026] In this embodiment, refer to Figure 4 The first air outlet 11 has an arc-shaped air outlet plate inside to reduce airflow impact, further reduce wind loss and noise.

[0027] In this embodiment, refer to Figure 2 and Figure 3 The distance between the arc-shaped air guide plate 12 and the fan 2 gradually increases in the counterclockwise direction, further ensuring that the vortex air field inside the box is more stable.

[0028] In this embodiment, refer to Figures 3 to 5 The air regulating mechanism 4 includes a handle and a linkage assembly. The handle, linkage assembly, and adjusting flap are connected in sequence. The handle and linkage assembly work together to rotate the adjusting flap 5 to adjust the airflow to the first air outlet 11 and the second air outlet 10. The air regulating mechanism can also adopt a cylinder or electric push rod structure. The push rod end of the cylinder or electric push rod drives the rotation of the adjusting flap 5 to achieve automatic flipping control of the adjusting flap.

[0029] The working process of this utility model:

[0030] During operation, the static pressure box starts the fan 2. As the fan blades rotate, they drive the surrounding air to flow and form a vortex wind field. The arc-shaped air guide plate 12 guides the air generated by the fan into the ventilation duct 13. The air flows out of the ventilation duct 13 and is stabilized by the flow stabilizer plate 3 before flowing from the first air outlet 11 and the second air outlet 10 to the blower nozzle of the setting machine, thereby drying the upper and lower surfaces of the fabric. When it is necessary to reduce the air volume of the first air outlet 11, the air adjustment mechanism 4 drives the adjustment flap 5 to rotate, thereby reducing the opening of the air inlet of the first air outlet 11, reducing the air flow to the first air outlet 11, and relatively increasing the air flow to the second air outlet 10.

[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
