[0030] Method of use and working principle: To ensure the connection between the air inlet 1, fixed sleeve 2, flow control device 3, flow guide member 4, connecting pipe 5 and flow direction adjusting mechanism 6 is stable, check if the sealing part (such as the sealing ring 404) is sealed well, prevent air leakage, equipment debugging: debug the electric telescopic rod 301 and motor 601, ensure they can operate normally, power on the electric telescopic rod 301 and motor 601, check if the telescopic rod 301 telescopes smoothly and the motor 601 rotates smoothly, parameter setting: according to actual needs, determine the required air flow and flow direction, which can be set by controlling the telescopic length of the electric telescopic rod 301 to set the air flow, and by controlling the rotation angle of the motor 601 to set the air flow direction, open air supply: open the air supply source, let the air enter the system from the air inlet 1, flow regulation: adjust the air flow with the electric telescopic rod 301, if you need to increase the air flow, make the electric telescopic rod 301 lengthen, let the flow limiting sleeve 305 and the limiting hole 307 on the flow control inlet 306 coincide to increase the area.If the air flow needs to be reduced, the electric telescopic rod 301 is shortened to reduce the overlapping area of the limiting hole 307, and the air flow is adjusted by the motor 601. By controlling the forward and reverse rotation and the rotation angle of the motor 601, the gear 603, the gear ring 604, the sliding column 605, the sliding sleeve 606, the transmission rod 607 and the flow guide plate 608 are driven to act, so as to change the flow direction of the air. Flow monitoring: During the operation of the system, the air flow is continuously monitored to see if it is stable at the set value. If the flow fluctuates, the telescopic length of the electric telescopic rod 301 should be adjusted in time. Observe whether the air flow meets the set requirements. If the flow direction deviates, the rotation angle of the motor 601 should be adjusted in time. Regularly check the operating conditions of each part to see if there are problems such as wear and looseness. Timely maintenance and replacement, turn off the air supply: first turn off the air supply source, stop supplying air to the system, restore the electric telescopic rod 301 and the motor 601 to the initial position, and prepare for the next use. Working principle: After the air enters the system from the air inlet 1, it will first reach the fixed sleeve 2. The flow guide member 4 in the fixed sleeve 2 begins to work. The connecting piece 401 connects the sealing plate 402 and the mounting ring 403. The sealing ring 404 between the sealing plate 402 and the mounting ring 403 ensures that the air does not leak. The mounting ring 403 is connected to the flow splitting assembly 406 through the connecting column 405. The flow splitting assembly 406 evenly distributes the incoming air, allowing the air to pass through the communication groove 21 into the flow control device 3 in a more orderly manner. After the flow control air enters the flow control device 3, the electric telescopic rod 301 begins to work. The output end of the electric telescopic rod 301 drives the connecting plate 302 to move. The connecting plate 302 drives the sliding sealing plug 304 to slide in the flow limiting sleeve 305 through the connecting rod 303. The flow limiting sleeve 305 and the outer surface of the flow control inlet 306 are provided with limiting holes 307. When the sliding sealing plug 304 slides, the overlapping area of the limiting hole 307 changes. The larger the overlapping area, the larger the cross-sectional area of the air passing through, and the larger the air flow. Conversely, the smaller the overlapping area, the smaller the air flow. This way, the air flow is accurately controlled. After the air is transported and the flow direction is adjusted, the air enters the connecting pipe 5, and then reaches the flow direction adjusting mechanism 6. The motor 601 in the flow direction adjusting mechanism 6 starts. The output end of the motor 601 drives the gear 603 to rotate. The gear 603 and the gear ring 604 are meshed with each other, so that the gear ring 604 rotates. The gear ring 604 drives the sliding column 605 to slide in the sliding sleeve 606. The sliding sleeve 606 drives the flow guide plate 608 to rotate through the transmission rod 607. By controlling the rotation direction and angle of the motor 601, the angle of the flow guide plate 608 can be accurately changed, so that the air flow direction can be flexibly adjusted, and the air can be transported to the corresponding position according to the requirements of the system.

[0031] The wiring diagram of the electric telescopic rod 301, the sliding sealing plug 304 and the motor 601 is common knowledge in the field, and its working principle is a known technology, and the model is selected according to actual use, so the control mode and wiring arrangement of the electric telescopic rod 301, the sliding sealing plug 304 and the motor 601 are not explained in detail.

Any skilled person in the art can modify or change the above disclosed technology content to equivalent embodiments applied to other fields. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model without departing from the technical scheme of the utility model still falls within the protection scope of the utility model technical scheme.
