[0001] The present application belongs to the field of ventilation equipment, in particular to a spiral air duct noise reduction type air volume adjustable air distributor. BACKGROUND

[0002] The air distributor is an air distribution device installed at the end of the room in the ship, aviation and building heating ventilation and air conditioning system. Its core function is to send the processed air (supply air) into the room in a comfortable, uniform and quiet manner, and to induce indoor air mixing, so as to form a uniform and comfortable temperature, humidity and air velocity environment in the personnel activity area.

[0003] The patent with publication number CN112648682B discloses a ventilation equipment, especially a kind of air distributor convenient for adjusting the direction of air outlet, which comprises an air distributor body, an air outlet wall is arranged on one side of the air distributor body, an air outlet end cover is rotationally connected to the side of the air outlet wall away from the air distributor body, an air outlet is formed on the air outlet end cover, a main air guide plate for guiding airflow is rotationally connected in the air outlet, the main air guide plate is located at the center of the air outlet, a pair of air guide plate groups are arranged on both sides of the main air guide plate in the air outlet, a rack is fixedly connected to the inner side of the air outlet end cover, the rack is arranged in a ring shape, a motor is arranged on the outer side of the air outlet wall to drive the rotation of the rack, the drive shaft of the motor penetrates the air outlet wall, one end of the drive shaft of the motor is fixedly connected with a gear, and the gear is engaged with the rack. The patent has the effect of making the air blown out of the air distributor body rotate around the air outlet, making the air distributor more uniform in adjusting the indoor air, reducing the possibility of local temperature being too low or too high, and improving the comfort of the air distributor in use.

[0004] However, the above technical solution still has the following shortcomings in actual application: By driving the rotation of the air guide plate to adjust the air outlet direction and the air outlet volume, when the air supply is stopped during use, the angles of multiple air guide plates need to be adjusted until the edges of adjacent air guide plates are fitted, so that the air outlet can be covered by the air guide plate to ensure the sealing effect. However, since the gas may contain hard impurities such as metal particles, even if the gas is filtered, it is difficult to ensure that the gas does not contain impurities, and when the gas moves, the impurities are easily attached to the edge of the air guide plate. When the air guide plate covers the air outlet, since the edges of adjacent air guide plates are fitted, the edges of the air guide plates will extrude the impurities, which not only easily causes the air guide plates to be stuck, affecting the sealing effect, but also may cause the edges of the air guide plates to be damaged due to extrusion, thereby affecting the use of the air guide plates.

[0016] The beneficial effects of this invention are as follows: 1.

[0019] 4. The spiral air duct noise reduction type air volume adjustable air distributor according to the application utilizes the compression type collecting assembly, when the push plate scrapes off the impurities attached to the edge of the air deflector, the pressing plate pushes the impurities into the inner cavity of the collecting box and seals the collecting box, thereby avoiding the situation that the scraped impurities fall to the edge of the air deflector on the other side, and then repeatedly attach the impurities, affecting the cleaning effect. And when the pressing plate is in contact with the impurities, sliding occurs, at this time the spring deforms, and the reaction force can provide a buffer for the pressing plate, which can not only compress the impurities to reduce the volume of the impurities for subsequent collection, but also avoid the structure from being damaged due to excessive pressure between the pressing plate and the impurities.

DETAILED DESCRIPTION

Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Please refer to Figures 1-17 , the present application provides a technical scheme: spiral air duct noise reduction type air volume adjustable air distributor, including mounting seat 2, mounting seat 2 one side end face through bolt fixed installation has shell 1, mounting seat 2 middle part penetrates fixedly connected with air outlet 4, air outlet 4 inner cavity middle part fixedly connected with connecting block 6, connecting block 6 on the circumferential direction evenly distributed and rotationally arranged with multiple air deflectors 5, air deflector 5 is fan-shaped, air deflector 5 one side rotationally arranged on air outlet 4, air outlet 4 is also provided with closed anti-jamming assembly; Closed anti-jamming assembly includes multiple sliding plates 7, multiple sliding plates 7 are divided into two groups, two groups of sliding plates 7 are different in angle, two groups of sliding plates 7 are located on both sides of connecting block 6, and two groups of sliding plates 7 are evenly distributed along the circumferential direction of air outlet 4 and are slidably connected thereto, and the push plate 25 is slidably connected to the sliding groove on one side of the sliding plate 7.

[0025] In this embodiment, as shown in Figures 4-12 , Figure 17 , one end of the air outlet 4 is fixedly connected with the spiral air duct 3, and the spiral air duct 3 is provided with a continuous spiral curved surface inside.

[0026] One end of the air deflector 5 is fixedly connected with the gear one 18, the transmission ring one 8 is slidably sleeved on one side of the outer wall of the air outlet 4, the transmission ring one 8 is evenly distributed and fixedly connected with multiple rack one 19 on the outer circle in the circumferential direction, and each gear one 18 is meshed with a rack one 19.

[0027] The transmission ring 8 is screw-connected with a threaded rod 14 at one side, and the threaded rod 14 is rotatably arranged on the air outlet 4 at two ends. The air outlet 4 is fixedly connected with a motor 15 at one side of the outer wall, and the output end of the motor 15 is fixedly connected with one end of the threaded rod 14.

[0028] One end of the one-side sliding plate 7 is fixedly connected with a connecting rod 10, and one end of the other-side sliding plate 7 is fixedly connected with a sliding rod 11. The connecting rod 10 and the sliding rod 11 are connected in a plug-in and sliding manner.

[0029] One end of the one-side sliding plate 7 is rotatably provided with a connecting rod 22, one end of the connecting rod 22 is rotatably provided with a connecting rod 23, and one end of the connecting rod 23 is rotatably arranged on the outer wall of the air outlet 4.

[0030] The outer wall of the air outlet 4 is slidably sleeved with a transmission ring 9, and a plurality of rack 20 are uniformly distributed and fixedly connected on one side of the transmission ring 9. One end of the connecting rod 23 is fixedly connected with a gear 21, and each gear 21 is meshed with one rack 20. The transmission ring 9 is screw-connected with a threaded rod 17 at one side, and the threaded rod 17 is rotatably arranged on the air outlet 4 at two ends. The outer wall of the air outlet 4 is fixedly connected with a motor 16 at one side, and the output end of the motor 16 is fixedly connected with one end of the threaded rod 17.

[0031] One end of the push plate 25 is screw-connected with a threaded rod 29, and the threaded rod 29 is rotatably arranged on the sliding plate 7 at two ends. The sliding plate 7 is fixedly connected with a motor 28 at one side of the recess, and the output end of the motor 28 is fixedly connected with one end of the threaded rod 29.

[0032] Specifically, in the prior art, the air outlet direction and the air outlet amount are adjusted by driving the air guide plate 5 to rotate. During use, when air supply is stopped, the angles of multiple air guide plates 5 need to be adjusted until the edges of adjacent air guide plates 5 are in close contact, so that the air outlet 4 can be covered by the air guide plate 5 to ensure the sealing effect. However, since the gas may contain hard impurities such as metal particles, even if the gas is filtered, it is difficult to ensure that the gas does not contain impurities. When the gas moves, the impurities are easily attached to the edges of the air guide plate 5. When the air guide plate 5 covers the air outlet 4, since the edges of adjacent air guide plates 5 are in close contact, the edges of the air guide plate 5 will extrude the impurities, which not only easily causes the air guide plate 5 to be stuck, affecting the sealing effect, but also may cause the edges of the air guide plate 5 to be damaged due to extrusion, thereby affecting the use of the air guide plate 5.

[0033] Therefore, in order to solve the above problems, the mounting seat 2 is installed at a proper position, and the spiral air duct 3 is communicated with the air outlet system, and the airflow can be sent out through the spiral air duct 3 and the air outlet 4. Since the continuous spiral curved surface is arranged in the spiral air duct 3, after the airflow enters the spiral air duct 3, the spiral curved surface guides the airflow along the trend of the curved surface, and the direction is changed smoothly and continuously. The flow is orderly, a large number of random vortexes are avoided, noise is suppressed, and the comfort of the surrounding personnel is improved.

[0034] In the air supply process, the transmission ring 8 can be slid on the air outlet 4 by the mode that the motor 15 drives the threaded rod 14 to rotate, so that the plurality of racks 19 simultaneously drive the plurality of gears 18 to rotate. When the gears 18 rotate, the corresponding air deflectors 5 also rotate, so that the angle of the air deflectors 5 can be adjusted to control the air volume, so as to meet different use requirements. Moreover, the air deflectors 5 in the scheme are fan-shaped, and the common rotation of the plurality of air deflectors 5 makes the air volume adjustment more uniform and more linear. The air outlet area changes synchronously with the opening, and the airflow is always uniformly diffused.

[0035] When it is necessary to seal the air outlet 4 by using the air deflectors 5, the air volume is first adjusted to the maximum. Since the air deflectors 5 are fan-shaped, the two sides of each air deflector 5 are parallel to the adjacent sliding plates 7. Then, the transmission ring 9 is slid on the air outlet 4 by the mode that the motor 16 drives the threaded rod 17 to rotate, so that the plurality of racks 20 simultaneously drive the plurality of gears 21 to rotate. Under the transmission cooperation of the connecting rods 23 and 22, the sliding plates 7 are slid on the air outlet 4. Since the two groups of sliding plates 7 are connected through the connecting rod 10 and the sliding rod 11, the two groups of sliding plates 7 simultaneously move, and the connecting rod 10 and the sliding rod 11 relatively slide. Then, the sliding plates 7 on the two sides move along the edges of the air deflectors 5, until the two ends of the push plate 25 are aligned with the two ends of the edges of the air deflectors 5, and the end face of one side of the push plate 25 is flush with the edge end face of the air deflector 5. At this time, the push plate 25 is slid along the edge of the air deflector 5 by the mode that the motor 28 drives the threaded rod 29 to rotate, and the impurities attached to the edge of the air deflector 5 are scraped off by the push plate 25. Then, the plurality of sliding plates 7 are reset, and when the sliding plates 7 are not working, the end portions thereof are located at the edges of the air outlet 4, and do not block the air outlet. At this time, the air deflectors 5 are closed again. Since the impurities on the edges of the air deflectors 5 are removed, the air deflectors 5 are effectively prevented from being stuck by the impurities, and the sealing effect is affected. Moreover, the edges of the air deflectors 5 are also prevented from being pressed to damage the impurities, and the service life of the air deflectors 5 is improved.

[0036] In the embodiment, as shown in Figure 9 , Figures 11-16 , the compression type collecting assembly is further included. The compression collection assembly includes a collection box 24 that is fixedly installed on one side of the sliding plate 7 by bolts, a baffle 27 that is inserted into and slidably connected to one side of the collection box 24, and a pressure plate 26 that is inserted into and slidably connected to one side of the push plate 25.

[0037] One end of the baffle 27 is threadedly connected to a threaded rod 13. Both ends of the threaded rod 13 are rotatably mounted on the sliding plate 7. A motor 4 30 is fixedly connected to one side of the sliding plate 7. The output end of the motor 4 30 is fixedly connected to one end of the threaded rod 13. A spring 12 is fixedly connected to one side of the pressure plate 26. The other end of the spring 12 is fixedly connected to the inner wall of the push plate 25.

[0038] Specifically, in the above embodiment, although the push plate 25 can be used to scrape off the impurities on the edge of the air guide plate 5, in order to ensure uniform airflow, the air guide plate 5 is arranged around the air outlet 4. Therefore, the scraped impurities may fall to the edge of the air guide plate 5 on the other side, resulting in repeated adhesion of impurities, which in turn affects the cleaning effect.

[0039] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Before the pusher plate 25 moves along the edge of the guide plate 5, the edge of the guide plate 5 is located between the pusher plate 25 and the collection box 24, and the pressure plate 26 is aligned with the inner cavity of the collection box 24. When the pusher plate 25 moves laterally, it uses the pressure plate 26 to scrape along the edge of the guide plate 5 and push the impurities into the inner cavity of the collection box 24. At the same time, when the pressure plate 26 comes into contact with the impurities, the pressure plate 26 will slide, and the spring 12 will deform. Under the effect of the reaction force of the spring 12, the pressure plate 26 will be buffered, which can both compress the impurities to reduce their volume and facilitate subsequent collection, and prevent structural damage caused by excessive pressure between the pressure plate 26 and the impurities. Then the pressure plate 26 is removed from the collection box 24, and the motor 30 drives the threaded rod 13 to rotate, causing the baffle 27 to slide on the collection box 24, closing the opening of the collection box 24 and preventing impurities from falling out. Then repeat the above operation. Each time cleaning is performed, the impurities will be sealed in the collection box 24, thus preventing the impurities from falling onto the edge of the air guide plate 5 on the other side and repeatedly adhering to the surface, which would affect the cleaning effect. Since the collection box 24 can be removed with bolts, the impurities in the collection box 24 can be removed periodically.

[0040] Working Principle: The mounting base 2 is installed in a suitable position, and the spiral duct 3 is connected to the air outlet system. Airflow can be delivered through the spiral duct 3 and the air outlet 4. Because the spiral duct 3 has a continuous spiral curved surface inside, after the airflow enters the spiral duct 3, the spiral curved surface guides the airflow along the direction of the surface, smoothly and continuously changing direction. This orderly flow avoids a large number of random vortices, thus suppressing noise and improving the comfort of surrounding personnel. During air delivery, the transmission ring 8 slides on the air outlet 4 by rotating the threaded rod 14 driven by the motor 15. This causes multiple racks 19 to simultaneously drive multiple gears 18 to rotate. When the gears 18 rotate, their corresponding guide plates 5 also rotate, allowing adjustment of the airflow angle to control the air volume and meet different usage requirements. Furthermore, the guide plates 5 in this design are fan-shaped, and the simultaneous rotation of multiple guide plates 5 makes the airflow adjustment more uniform and linear. The air outlet area changes synchronously with the opening, ensuring that the airflow is always evenly diffused. When it is necessary to seal the air outlet 4 using the air guide plate 5, the air volume is first adjusted to the maximum. Since the air guide plate 5 is fan-shaped, each air guide plate 5 is parallel to the adjacent sliding plate 7 on both sides. Then, the motor 216 drives the threaded rod 317 to rotate, causing the transmission ring 29 to slide on the air outlet 4. The rack 20 drives multiple gears 21 to rotate simultaneously, so that the sliding plate 7 can slide on the air outlet 4 under the transmission cooperation of the connecting rod 23 and the connecting rod 12. Furthermore, since the two sets of sliding plates 7 are connected by the connecting rod 10 and the sliding rod 11, the two sets of sliding plates 7 will move simultaneously, and the connecting rod 10 and the sliding rod 11 will slide relative to each other. The sliding plates 7 on both sides move along the edge of the air guide plate 5 until the two ends of the push plate 25 are aligned with the two ends of the edge of the air guide plate 5, and one end face of the push plate 25 is flush with the end face of the edge of the air guide plate 5. At this time, the push plate 25 can slide along the edge of the air guide plate 5 by rotating the threaded rod 29 driven by the motor 3 28. The push plate 25 scrapes away the impurities attached to the edge of the air guide plate 5, and then drives the multiple sliding plates 7 to reset. When the sliding plates 7 are not working, their ends are located at the edge of the air outlet 4, and will not obstruct the air outlet. At this time, the air guide plate 5 is then driven to close. Since the impurities on the edge of the air guide plate 5 have been removed, the situation where the air guide plate 5 is stuck due to impurities, thus affecting the sealing effect, is effectively avoided. It also avoids the situation where the air guide plate 5 is damaged due to the extrusion of impurities on the edge, which helps to improve the service life of the air guide plate 5.Before the push plate 25 moves along the edge of the air deflector 5, the edge of the air deflector 5 is located between the push plate 25 and the collecting box 24, and the pressing plate 26 is aligned with the inner cavity of the collecting box 24. When the push plate 25 moves horizontally, the impurities on the edge of the air deflector 5 will be scraped by the pressing plate 26 and pushed into the inner cavity of the collecting box 24. At the same time, when the pressing plate 26 abuts against the impurities, the pressing plate 26 will slide, and the spring 12 will be deformed. The spring 12 can provide a buffer for the pressing plate 26 under the effect of the reaction force of the spring 12, which can compress the impurities to reduce the volume of the impurities, facilitate subsequent collection, and avoid damage to the structure due to excessive pressure between the pressing plate 26 and the impurities. Then the pressing plate 26 is removed from the collecting box 24, the threaded rod 13 is rotated by the motor 30, and the baffle 27 slides on the collecting box 24 to close the opening of the collecting box 24, so as to prevent the impurities from falling out. Then the above operation is repeated, and the impurities will be closed in the collecting box 24 during each cleaning operation.
