Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example

[0027] See also Figure 1-7 The present invention provides the following technical solutions: an air supply box, comprising a box body 1, a flange interface 2 is provided at the rear end of the box body 1, a connecting socket 3 is provided at the front end of the box body 1, a reinforcing plate 31 is fixed inside the connecting socket 3, a diffuser panel 4 is rotatably installed at one end of the inner side of the connecting socket 3 away from the box body 1, and a symmetrical press-type lock 5 is installed between the other end of the diffuser panel 4 and the inside of the box body 1, a filter 6 is fixedly installed inside the box body 1, and a sealing strip 7 is provided at the connection with the box body 1, a flow equalizing orifice 8 is provided at the connection between the box body 1 and the flange interface 2, and hanging hooks 9 are fixedly provided at the four corners of the rear side of the box body 1, and flow control devices that cooperate with each other are provided between the box body 1, the inside of the flange interface 2 and the outside of the air box, and the flow control device is divided into a cut-off part and a control part. The rated air volume (maximum air volume) of the air box in this embodiment is 1500m 3 / H; initial resistance is not more than 220Pa; hook 9 efficiency 99.99%@0.3um.

[0028] Specifically, the intercepting part includes a guide plate 10 fixed inside the flange interface 2 and evenly arranged in sequence up and down, a receiving groove 11 running through the guide plate 10, and a intercepting plate 12 inserted and slid inside the receiving groove 11 and an internal threaded seat 13 fixed at the upper end of the flange interface 2. It also includes a screw rod 14 located inside the internal threaded seat 13 and a polygonal sleeve 15 fixed at the upper end of the screw rod 14. A motor bracket 16 is fixed on the flange interface 2, a servo motor 17 is fixed on the motor bracket 16, and a polygonal pin 18 is fixed to the output end of the servo motor 17.

[0029] Specifically, the intercepting plate 12 is formed by combining a number of baffles evenly distributed above and below and a connecting rod passing through the baffle. The gap between two adjacent guide plates 10, the height of the receiving groove 11, and the height of the baffle are all the same. A connecting rod 141 is also fixedly provided at the lower end of the screw rod 14. The screw rod 14 is connected to the middle of the top end of the intercepting plate 12 through the connecting rod 141, and they rotate with each other. The screw rod 14 is threadedly connected to the internal threaded seat 13.

[0030] Specifically, the polygonal pin 18 is always inserted into the polygonal sleeve 15, and the internal thread seat 13, the screw rod 14, the polygonal sleeve 15, and the polygonal pin 18 are cocentric.

[0031] Specifically, the end of the guide plate 10 close to the air inlet of the bellows is a strip-shaped conical structure. In this embodiment, the conical structure does not affect the flow rate, but cooperates with the internal thread seat 13 to play a flow interception role when intercepting the flow.

[0032] Specifically, the servo motor 17 transmits power to the screw 14 through the polygonal pin 18 and the polygonal sleeve 15. The screw 14 drives the intercepting plate 12 to move up and down in the receiving groove 11 inside the guide plate 10 through the spiral with the internal threaded seat 13 and the connecting rod 141. The bellows controls the flow rate by raising and lowering the intercepting plate 12 inside the guide plate 10. In this embodiment, the flow rate is controlled to make the environment more comfortable.

[0033] Specifically, the servo motor 17 transmits power to the screw rod 14 through the polygonal pin 18 and the polygonal sleeve 15. The screw rod 14 drives the intercepting plate 12 to move up and down in the receiving groove 11 inside the guide plate 10 through the spiral with the internal thread seat 13 and the connecting rod 141. In this embodiment, the screw rod 14 and the polygonal sleeve 15 do not affect the lifting and lowering of the screw rod 14, and also ensure the stable transmission of the power of the servo motor 17.

[0034] Specifically, the control part includes a differential pressure transmitter 19 installed inside the box 1 and a controller 20 installed outside the bellows. The two pressure ports of the differential pressure transmitter 19 are respectively located at the two ends of the intake and exhaust of the box 1. The differential pressure transmitter 19 is electrically connected to the controller 20, and the controller 20 is also electrically connected to the servo motor 17.

[0035] Specifically, the differential pressure transmitter 19 transmits data to the controller 20, and the controller 20 controls the start and stop and rotation direction of the servo motor 17 according to the data size. In this embodiment, the controller 20 controls the start and stop and direction of the servo motor 17 through the numerical value transmitted by the differential pressure transmitter 19, and then realizes the flow control function through the interception component.

[0036] Specifically, the box body 1, flange interface 2, and connecting socket 3 are integrally formed of anodized aluminum profiles. The length, width, and height of the bellows are 685mm*685mm*180, the length, width, and height of the flange interface 2 are 400mm*320mm*10mm, the diameter of the flow equalizing orifice plate 8 is 250mm, and the size of the hanging hook 9 in this embodiment is 630mm*630*80mm.

[0037] The working principle and usage process of the present invention are as follows: the filter 6 is fixedly installed inside the box body 1 through a sealing strip 7. One end of the diffuser panel 4 is connected to the box body 1 through a rotating shaft, and the other end is connected to the box body 1 through two symmetrically distributed push-type lock buckles 5. The push-type lock buckle 5 is pressed once to lock it, and it pops out when pressed again. The two filters 6 are independent structures. When in use, both filters 6 need to be pressed once to realize the opening and closing of the diffuser panel 4. When installing the bellows, the color steel plate is directly inserted into the connecting socket 3 through the opening on the outside of the connecting socket 3. A differential pressure transmitter 19 is installed inside the box body 1. The two pressure interfaces on the differential pressure transmitter 19 are respectively located at the inlet and exhaust ends of the bellows. Then a controller 20 is installed outside the bellows. The differential pressure transmitter 19 is electrically connected to the controller 20, and the servo motor 17 is also electrically connected to the controller 20. The differential pressure transmitter 19 transmits a signal to the controller 20, and the controller 20 controls the forward and reverse start and stop of the servo motor 17 according to the model;

[0038] Working principle of flow automatic control device: differential pressure transmitter 19 collects pressure data in real time and transmits the data to controller 20. Controller 20 controls the forward and reverse rotation of servo motor 17 by the high and low of the transmitted data. If the intake and exhaust support forms a positive pressure state, controller 20 controls servo motor 17 to rotate forward. If a negative pressure state is formed, controller 20 controls servo motor 17 to rotate reversely. After receiving the command from controller 20, servo motor 17 outputs power through polygonal pin 18. Polygonal pin 18 drives polygonal sleeve 15 and screw rod 14 to rotate. Screw rod 14 rotates by contacting with inner The spiral inside the threaded seat 13 rises and falls inside it, and at the same time, the connecting rod 141 at the bottom of the screw rod 14 drives the intercepting plate 12 to follow the movement inside the receiving groove 11 in the guide plate 10. The intercepting plate 12 moves between the inside of the receiving groove 11 and the gap between the two adjacent guide plates 10. When the intercepting plate 12 is completely moved into the inside of the receiving groove 11, the inside of the bellows is in the maximum flow state. When the intercepting plate 12 is completely located in the gap between the two adjacent guide plates 10, the bellows is closed, and the movement size of the intercepting plate 12 is controlled according to the difference of the pressure differential transmitter 19.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
