Description

Technical Field

[0001] This utility model relates to the field of ventilation control, and in particular to an air volume distributor that can automatically close. Background Technology

[0002] An air volume distributor is a device used in ventilation or air conditioning systems. Its main function is to distribute the supplied air evenly to different areas or spaces to ensure that the air circulation and temperature distribution in the entire environment achieve the expected results.

[0003] Existing airflow distributors typically employ manual adjustment or fixed opening designs, which have several significant drawbacks. First, manual adjustment is inefficient in large ventilation or air conditioning systems, failing to respond promptly to airflow changes and resulting in uneven air distribution. Second, fixed opening designs cannot flexibly adjust airflow according to actual needs, especially when airflow fluctuations are significant, making it difficult to maintain stable airflow distribution. This may lead to poor air circulation or over-ventilation in certain areas, affecting comfort and energy efficiency.

[0004] Therefore, it is necessary to design an airflow distributor that can automatically close to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides an air volume distributor that can automatically close.

[0006] The technical solution of this utility model is as follows: An automatically closing airflow distributor includes a manifold, an inlet pipe, an outlet pipe, a flow regulating plate, a worm gear, a worm, a motor, a fixed base, a flow guide plate, and an elastic element. The manifold has a cavity inside, and several air outlets are opened inside the manifold, with the air outlets flowing in opposite directions to the cavity. An inlet pipe is connected to the top of the manifold, and an outlet pipe is connected to the end of each outlet. A flow regulating plate is rotatably connected to one end of each outlet pipe. A worm gear is provided at the rotatable connection point between each flow regulating plate and the manifold. A worm is rotatably provided inside the manifold corresponding to the outer side of each outlet pipe. Each worm gear is rotatably engaged with the connected worm. A motor is provided above each worm inside the manifold, and the output shaft of each motor is connected to the corresponding worm below. Fixed bases are provided on both sides of the center of the bottom of the manifold. A flow guide plate is slidably provided on the upper part of the two fixed bases. An elastic element is sleeved on the outer side of each fixed base.

[0007] Preferably, the top surface of the diversion plate is horizontal, while the upper sides of the diversion plate are inclined, and each side corresponds to the air outlet of each air duct.

[0008] Preferably, the device also includes a sleeve, a bidirectional screw, a knob, and clamps. Each air outlet pipe is fitted with a sleeve, and a bidirectional screw is threaded onto the lower part of each sleeve. A knob is rotatably mounted in the middle of each bidirectional screw, and clamps for clamping the connecting pipe are rotatably mounted at both ends of each bidirectional screw. The upper parts of the two clamps at the same location slide on the inner side of the corresponding sleeve and are close to the outer side of the corresponding air outlet pipe.

[0009] Preferably, it also includes a fixing ring, a filter plate and a retaining ring. A fixing ring is provided in the middle of each air outlet duct, a filter plate is embedded in each fixing ring, and a retaining ring is inserted into the outside of each fixing ring. Each retaining ring is framed within the corresponding filter plate.

[0010] Preferably, the fixing ring has several evenly arranged locking holes inside, and the locking ring has a corresponding insertion rod for each locking hole, so that the two are compatible.

[0011] Preferably, it also includes a pry bar, with a pry bar recessed inward on the outer side of each retaining ring.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example: An automatically closing airflow distributor, such as... Figures 1-6 As shown, the system includes a manifold 1, an inlet pipe 2, an outlet pipe 3, a flow control plate 4, a worm gear 5, a worm 6, a motor 7, a fixed base 8, a guide plate 9, and an elastic element 10. The manifold 1 has an internal cavity with six outlets, each of which is convective with the cavity. The top of the manifold 1 is connected to the inlet pipe 2, which connects to an external air supply source to provide airflow to the system. The ends of the six outlets are connected to the outlet pipes 3, which guide the airflow to designated areas, achieving directional transmission of air volume. Each outlet pipe 3 is rotatably connected to a flow control plate 4 at one end. The flow control plate 4 changes its angle by rotating to control the airflow in the outlet pipe 3. Worm gears 5 are provided at the rotatable connection points between each end of the flow control plate 4 and the manifold 1. Inside the manifold 1, corresponding to the outer side of each outlet pipe 3, a worm 6 is rotatably installed, with each worm gear 5 meshing with the connected worm 6. The worm gear 6 is driven to rotate by the motor 7. Through meshing with the worm wheel 5, it drives the flow regulating plate 4 to rotate. Inside the manifold 1, a motor 7 is installed above each worm gear 6. The motor 7 provides electric power to drive the worm gear 6 to rotate, thereby controlling the angle of the flow regulating plate 4. The output shaft of each motor 7 is connected to the corresponding worm gear 6 below. Fixed seats 8 are installed on both sides of the bottom center of the manifold 1. The fixed seats 8 support the flow guiding plate 9 and allow it to slide up and down when the airflow changes. The flow guiding plate 9 is slidably installed in the upper part of the two fixed seats 8. The flow guiding plate 9 adapts to changes in airflow and ensures uniform airflow distribution by moving up and down. The top surface of the flow guiding plate 9 is set horizontally, while the upper sides of the flow guiding plate 9 are set at an inclination. Each side corresponds to the air outlet of each air outlet pipe 3. Elastic elements 10 are sleeved on the outside of the fixed seats 8. The elastic elements 10 provide restoring force so that the flow guiding plate 9 returns to its original position when the airflow weakens.

[0024] like Figure 1 and Figures 6-7As shown, it also includes a sleeve 11, a bidirectional screw 12, a knob 13, and a clamping block 14. Each air outlet pipe 3 is fitted with a sleeve 11. The sleeve 11 fixes the bidirectional screw 12 and provides a sliding track for the clamping block 14. The lower part of each sleeve 11 is threaded with a bidirectional screw 12. The bidirectional screw 12 changes the position of the clamping block 14 by rotating, so as to clamp or release the external pipe. The middle part of each bidirectional screw 12 is rotatably provided with a knob 13. The knob 13 controls the rotation of the bidirectional screw 12, which facilitates the installation and disassembly of the connecting pipe. Both ends of each bidirectional screw 12 are rotatably provided with clamping blocks 14 for clamping the connecting pipe. Under the action of the bidirectional screw 12, the clamping blocks 14 clamp or release the external pipe. The upper parts of the two clamping blocks 14 at the same location slide on the inner side of the corresponding sleeve 11 and are close to the outer side of the corresponding air outlet pipe 3.

[0025] like Figure 1 and Figures 6-7 As shown, it also includes a fixing ring 15, a filter plate 16, and a retaining ring 17. Each air outlet duct 3 has a fixing ring 15 in the middle. The fixing ring 15 installs and fixes the filter plate 16, and provides a retaining hole 1501 for the retaining ring 17 to fix it. The fixing ring 15 has several evenly arranged retaining holes 1501 inside. The retaining ring 17 has a corresponding insert rod on the retaining hole 1501. The two are compatible. Each fixing ring 15 has a filter plate 16 embedded in it. The filter plate 16 filters impurities in the air to ensure clean air outlet. Each fixing ring 15 has a retaining ring 17 inserted on the outside. Each retaining ring 17 covers the corresponding filter plate 16 inside it. The retaining ring 17 can lock or release the filter plate 16 by rotating it, which facilitates the installation and replacement of the filter plate.

[0026] like Figure 7 As shown, it also includes a lever 18. Each retaining ring 17 has a lever 18 that is recessed inward on the outer side. The lever 18 provides an operating point to facilitate the installation or removal of the filter plate 16 by rotating the retaining ring 17.

[0027] When airflow adjustment is needed, the starting motor 7 drives the worm gear 6 to rotate. The worm gear 6 meshes with the worm wheel 5, which in turn drives the flow control plate 4 to rotate. By changing the angle of the flow control plate 4, the airflow through the outlet pipe 3 can be controlled. Multiple motors 7 can control different outlet pipes 3 respectively, achieving precise airflow distribution. When airflow changes, the guide plate 9 slides within the fixed seat 8. When the airflow increases, the guide plate 9 moves downward under the pressure of the airflow, compressing the elastic element 10; when the airflow decreases, the elastic force of the elastic element 10 will cause the guide plate 9 to return to its original position, thus ensuring uniform airflow distribution even under conditions of large airflow fluctuations. When it is necessary to connect the outer pipe to the outlet pipe 3... First, insert the outer connecting pipe into the air outlet pipe 3. Then, rotate the knob 13 to move the clamps 14 at both ends of the double-ended screw 12 inward to clamp the outer connecting pipe. Conversely, when disassembly is required, rotate the knob 13 in the opposite direction to move the clamps 14 outward to loosen the outer connecting pipe, thus making it easy to disassemble. The filter plate 16 can filter impurities in the air and keep the air outlet clean. When installing the filter plate 16, place the filter plate 16 into the fixing ring 15, and then insert the insert rod on the retaining ring 17 into the retaining hole 1501 on the fixing ring 15. Rotate the retaining ring 17 until the insert rod is fully inserted into the retaining hole 1501. When replacing, simply rotate the retaining ring 17 to disengage the insert rod from the retaining hole 1501, and then remove the filter plate 16 for replacement.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
