Description

Technical Field

[0001] This utility model relates to the field of building decoration, specifically to an adjustable air outlet structure for an air conditioning system. Background Technology

[0002] With the improvement of residents' living standards and the frequent occurrence of extreme weather events, air conditioning systems have gradually transformed from a luxury item in the traditional consumer sector into a core infrastructure in modern buildings and daily life. These systems mainly include outdoor air conditioning units, indoor air conditioning units, air conditioning vents, power supplies, and refrigerant pipelines. Among these, air conditioning vents are a key component of the air conditioning system, responsible for delivering treated air into the room to ensure a uniform and comfortable indoor temperature. Traditional methods include fixed vents and adjustable (manual) vents.

[0003] However, traditional fixed air vents cannot be adjusted in direction and have dust accumulation problems; the mechanical parts of adjustable (manual) air vents are easily damaged, and the adjusting blades are prone to loosening after long-term use, requiring frequent manual adjustments to meet the needs, which is very inconvenient. On the other hand, the cold air blown directly from the air conditioner with fixed air vents can cause discomfort to people. In large spaces, hot and cold air are separated, with the bottom being too cold and the top too hot, making it impossible to achieve a uniform indoor temperature. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an adjustable air outlet structure for an air conditioning system. The structure uses gears to drive the support plate to rotate relative to the limiting plate, and then uses oscillation to drive the blades to rotate relative to the support plate, thereby achieving the function of adjusting the air speed.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adjustable air outlet structure for an air conditioning system includes an air outlet. Multiple adjusting devices for adjusting air speed are provided inside the air outlet. Each adjusting device includes a limiting plate connected to the inner wall of the air outlet. One side of the limiting plate is connected via a connecting rod to a support plate that can rotate longitudinally relative to the limiting plate. One side of the support plate is connected via a swing rod to blades that can rotate longitudinally relative to the limiting plate. The swing rod and the connecting rod are connected to the support plate via a rotating shaft. A drive gear is installed on the limiting plate, and a driven gear is installed on the support plate. The driven gear meshes with the drive gear, and a drive mechanism for driving the drive gear to rotate is also provided in the air outlet.

[0006] Optionally, the limiting plate is fixedly installed inside the air outlet, the connecting rod is rotatably connected to the limiting plate, and the swing rod is fixedly connected to the blade.

[0007] Optionally, the support plate is rotatably connected to the rotating shaft, and the rotating shaft is fixedly connected to both the connecting rod and the swing rod.

[0008] Optionally, multiple blades are provided, and the multiple blades are distributed sequentially along the length direction of the support plate, and the number of connecting rods, swing rods and rotating shafts corresponds to the number of blades.

[0009] Optionally, the drive mechanism includes a main shaft rotatably mounted inside the air outlet, the main shaft being perpendicular to the limiting plate, and a drive assembly on the main shaft corresponding to the number and position of the adjusting devices, and the drive assembly being used to drive the drive gear to rotate.

[0010] Optionally, the drive assembly includes a main bevel gear, a driven bevel gear, and a drive shaft. The drive shaft passes through the limiting plate, with one end connected to the driving gear and the other end connected to the driven bevel gear. The main bevel gear is mounted on the main shaft and meshes with the driven bevel gear.

[0011] Optionally, the plurality of adjustment devices are divided into two groups, and the two groups of adjustment devices are symmetrically distributed in the air outlet relative to the central cross-section of the main shaft.

[0012] Optionally, both the connecting rod and the swing rod adopt an arc-shaped structure, and a decorative air vent is installed at the end of the air outlet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) In this utility model, the support plate can be flipped relative to the limiting plate by the gear. During the flipping process, the support plate drives the rotating shaft through the connecting rod, and then the rotating shaft drives the swing arm to move, which finally drives the blade to flip relative to the support plate. By adjusting the blade angle, the wind speed of the air outlet can be adjusted. Compared with the existing manual adjustment structure, it is more convenient, can reduce the wear of mechanical parts, avoid the blade from loosening after long-term use, and can meet the dynamic wind speed matching requirements, reduce the generation of condensate, reduce maintenance difficulty, and extend the equipment life. (2) In this utility model, multiple adjustment devices in the same air outlet are driven by a main shaft to increase the corresponding number of drive components, thereby realizing the synchronous operation of multiple adjustment devices, simplifying the air outlet structure, and ensuring the consistency of wind speed adjustment among multiple devices.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0016] Example 1, as Figures 1-3 As shown, an adjustable air outlet structure for an air conditioning system includes an air outlet 1, a plurality of adjusting devices 3 are provided inside the air outlet 1, the plurality of adjusting devices 3 are distributed at equal intervals along a straight line and can be used to adjust the air speed of the air outlet 1, and a drive mechanism 4 is also provided inside the air outlet 1, the drive mechanism 4 is used to drive the adjusting devices 3 to operate.

[0017] The aforementioned adjusting device 3 includes a limiting plate 301, a support plate 302, and a blade 303. The support plate 302 is located between the limiting plate 301 and the blade 303, and the support plate 302 is connected to the limiting plate 301 via a connecting rod 304. The support plate 302 is connected to the blade 303 via a swing rod 305. The swing rod 305 and the connecting rod 304 are rotatably connected to the support plate 302 via the same rotating shaft 306, and the rotating shaft 306 is rotatably mounted on the support plate 302. The connecting rod 304 and the swing rod 305 are both fixedly connected to the rotating shaft 306.

[0018] The limiting plate 301 is fixedly installed inside the air outlet 1 and is fixedly connected to the inner wall of the air outlet 1. The connecting rod 304 is rotatably connected to the limiting plate 301, and the swing rod 305 is fixedly connected to the blade 303. The limiting plate 301 is rotatably mounted with a drive gear 307, and the support plate 302 is rotatably mounted with a driven gear 308, and the driven gear 308 and the drive gear 307 mesh with each other.

[0019] Specifically, the drive mechanism 4 is used to drive the drive gear 307 to rotate, which in turn drives the support plate 302 to flip relative to the limit plate 301 in the longitudinal direction through the rotation of the driven gear 308. When the support plate 302 flips, it drives the blade 303 to flip relative to the limit plate 301, and also drives the connecting rod 304 to make adaptive movements relative to the limit plate 301 and the support plate 302. Therefore, the connecting rod 304 will drive the rotating shaft 306 to rotate relative to the support plate 302 around its own axis, and further drive the swing rod 305 to swing relative to the support plate 302, and finally drive the blade 303 to flip relative to the support plate 302 in the longitudinal direction to achieve angle adjustment.

[0020] The angle adjustment of blade 303 can change the airflow path and resistance. When blade 303 is fully open (such as in a horizontal state), the airflow can pass through directly without changing direction, with minimal flow resistance. At this time, the airflow volume is the largest and the wind speed is the fastest. When blade 303 is gradually tilted (such as rotating upward or downward), the airflow needs to go around the edge of blade 303 to pass through. The path is lengthened, and the resistance increases accordingly, resulting in a reduction in the actual airflow volume and a decrease in wind speed.

[0021] Furthermore, each adjusting device 3 includes multiple blades 303, which are distributed sequentially along the length of the support plate 302. The number of connecting rods 304, rocker arms 305, and rotating shafts 306 corresponds to the number of blades 303. That is, each blade 303 is connected to the rotating shaft 306 through a rocker arm 305, and each rotating shaft 306 is connected to the limiting plate 301 through a connecting rod 304. This enables the synchronous rotation of multiple blades 303. The driving gear 307 and the driven gear 308 are cylindrical gears, and the driven gear 308 can be installed on one of the rotating shafts 306.

[0022] The support plate 302 is driven by gears to rotate relative to the limiting plate 301. During the rotation, the support plate 302 drives the rotating shaft 306 through the connecting rod 304, and then the rotating shaft 306 drives the swing arm 305 to move, which ultimately causes the blade 303 to rotate relative to the support plate 302. By adjusting the angle of the blade 303, the wind speed of the air outlet 1 can be adjusted. Compared with the existing manual adjustment structure, it is more convenient, reduces the wear of mechanical parts, prevents the blade 303 from loosening after long-term use, and can meet the dynamic wind speed matching requirements, reduce the generation of condensate, reduce maintenance difficulty, and extend the equipment life.

[0023] In addition, to facilitate the flipping motion, both the connecting rod 304 and the swing rod 305 adopt an arc-shaped structure, and a decorative air vent 2 is fixedly installed at the end of the air outlet 1 to beautify the air and make the indoor air outlet 1 more aesthetically pleasing.

[0024] In Example 2, based on Example 1, this utility model also proposes a specific structure for the drive mechanism 4.

[0025] like Figure 2 and Figure 4 As shown, the drive mechanism 4 includes a main shaft 401 rotatably mounted in the air outlet 1. The main shaft 401 is perpendicular to the limiting plate 301. The main shaft 401 is provided with drive components corresponding to the number and position of the adjustment devices 3, and the drive components are used to drive the drive gear 307 to rotate.

[0026] Specifically, a motor is installed on the outside of the air outlet 1. The output end of the motor is connected to the main shaft 401 to drive the main shaft 401 to rotate around its own axis. Multiple adjustment devices 3 in the same air outlet 1 are driven by a corresponding number of drive components on the main shaft 401, thereby realizing the synchronous operation of multiple adjustment devices 3, simplifying the air outlet structure, and ensuring the consistency of wind speed adjustment among multiple devices.

[0027] The drive assembly described above includes a main bevel gear 402, a driven bevel gear 403, and a drive shaft 404. The main bevel gear 402 is mounted on the main shaft 401 and meshes with the driven bevel gear 403. The drive shaft 404 passes through the limiting plate 301 and is rotatably connected to it. One end of the drive shaft 404 is connected to the driving gear 307, and the other end is connected to the driven bevel gear 403. When the main shaft 401 drives the main bevel gear 402 to rotate, the main bevel gear 402 then drives the driven bevel gear 403 to rotate through the meshing relationship. Finally, the driven bevel gear 403 drives the driving gear 307 to rotate through the drive shaft 404, thereby realizing the drive for the operation of the adjusting device 3.

[0028] Furthermore, the number of regulating devices 3 within the same air outlet 1 is even, and they can be divided into two groups. The two groups of regulating devices 3 are symmetrically distributed relative to the central cross-section of the main shaft 401. Through this structural design, by simultaneously adjusting the blade angles 303 of the two groups of regulating devices 3, the air can be guided to a specific area, such as precisely blowing towards the corner of the room, to achieve a more uniform ventilation or temperature control effect.

[0029] Working principle: The motor drives the main shaft 401 to rotate. The main shaft 401 drives the driven bevel gear 403 to rotate through the main bevel gear 402. The driven bevel gear 403 then drives the driving gear 307 to rotate through the transmission shaft 404. The main gear drives the driven gear 308 to rotate based on the meshing relationship. While the driven gear rotates around its own axis, it also rotates around the axis of the transmission shaft 404 as a whole. This causes the support plate 302 to rotate longitudinally relative to the limiting plate 301. When the support plate 302 rotates longitudinally, it causes the blade 303 to rotate relative to the limiting plate 301. At the same time, it also causes the connecting rod 304 to move relative to the limiting plate 301 and the support plate 302. Therefore, the connecting rod 304 will drive the rotating shaft 306 to rotate relative to the support plate 302 around its own axis. This will further drive the swing rod 305 to swing relative to the support plate 302. Finally, it will cause the blade 303 to rotate longitudinally relative to the support plate 302 to achieve angle adjustment.

[0030] In Example 3, based on the above examples, this utility model also proposes another structure for the adjustment device 3.

[0031] The connecting rod 304 of the adjusting device 3 is rotatably connected to the limiting plate 301. The swing rod 305 is fixedly connected to the blade 303. At the same time, the rotating shaft 306 is fixedly installed on the support plate 302. The connecting rod 304 is rotatably connected to the rotating shaft 306, and the swing rod 305 is fixedly connected to the rotating shaft 306. Therefore, the blade 303 is fixedly connected to the support plate 302 through the swing rod 305, and the ends of multiple blades 303 overlap and fit together in sequence.

[0032] Specifically, when the support plate 302 flips longitudinally, it can cause the blade 303 to flip relative to the limiting plate 301, thereby achieving overall angle adjustment. That is, the blade 303 and the support plate 302 can move synchronously, which can also play the role of adjusting wind speed.

[0033] In summary, this utility model proposes an adjustable air outlet structure for an air conditioning system, which breaks through the limitations of traditional air outlets. The rotation parameters of the main shaft 401 can be adjusted through an existing remote control system, thereby controlling the angle rotation gears (driving gear 307 and driven gear 308). The rotation of the gears drives the support plate 302 to flip relative to the limiting plate 301, thereby driving the blades 303 to adjust the angle, so as to achieve the purpose of adjusting the wind direction and wind speed. Secondly, it can achieve dynamic wind speed matching needs, optimize the uniformity of the indoor environment, reduce the generation of condensate, and reduce maintenance difficulty. By precisely controlling the air volume of air outlet 1, it reduces the load on the main unit and extends the equipment life. This air outlet structure can adapt to the use of various environments. It can meet the needs of high wind speed long-distance air supply in large spaces, as well as low wind speed diffusion in small spaces. By reducing energy consumption, it indirectly reduces the carbon emissions of the air conditioning system, thus achieving the goal of energy conservation and emission reduction.
