Description

Technical Field

[0001] This invention relates to the field of air distributor technology, specifically a marine combined air distributor. Background Technology

[0002] Marine combined air distributors refer to a type of air distribution terminal installed at the air supply end of a cabin, integrating primary air delivery and cabin air induction into the same terminal device. It is usually composed of air ducts, induced return air structures, and air outlet guide structures. Traditional marine air distributors often use fixed diffusers or simple adjustable grilles to achieve air supply temperature regulation and airflow organization optimization. Although fixed diffusers are simple and reliable in structure, their air outlet characteristics cannot be changed. While manually adjustable grilles can change the air direction, the adjustment depends on manual operation and cannot be linked with air supply parameters. Furthermore, by using induced air distributors, which utilize the Venturi effect, the negative pressure generated by the acceleration of primary air at the throat induces the mixing of cabin air with primary air, which can improve the uniformity of air supply temperature and promote indoor air circulation.

[0003] However, existing induced draft air distributors have fixed venturi throat dimensions and an unadjustable ratio of primary air volume to return air volume, making it impossible to dynamically match the temperature inside the cabin. When the required cooling capacity of the cabin decreases, the reduction in primary air volume will simultaneously cause a drop in throat negative pressure, which in turn reduces the induced return air volume. This results in an excessively low temperature of the mixed supply air, causing an uncomfortable feeling of cold air. Under high load conditions, although the primary air volume and return air volume are large, the mixing of primary air and return air is not sufficient or uniform due to the fixed throat structure. Furthermore, the air outlet guide state cannot be adjusted synchronously with the high-speed airflow, resulting in a still large supply air temperature difference and poor temperature uniformity at the far end of the cabin. This forces the air conditioning system to operate at higher loads to compensate for the local discomfort caused by the mismatch in supply air temperature and unreasonable airflow organization, resulting in unnecessary energy waste. Summary of the Invention

A support plate is fixedly connected to the surface of the neck pipe along a first direction. A cylinder is fixedly installed on the surface of the support plate along a third direction. The cylinder rod of the cylinder protrudes from the surface of the support plate and is slidably connected to the support plate. A connecting plate is fixedly connected to the cylinder rod along the surface of the third direction. A sliding pin is fixedly connected to the surface of the connecting plate near the neck pipe. The sliding pin is slidably connected in the guide groove. The adaptive mechanism includes a support rod, which is connected to the inner surface of the air outlet duct by screws. A support ring is fixedly connected to the end of the support rod away from the inner surface of the air outlet duct. A square rod is slidably connected inside the support ring along a third direction. An air collection hood is fixedly connected to the surface of the square rod along a third direction. A spring extending along a third direction is sleeved on the outer side of the square rod.

[0006] Preferably, the air inlet mechanism includes a square ring tube, which is fixedly sleeved on the outer surface of the air outlet duct. An exhaust hole is opened on the surface of the square ring tube opposite to the air outlet duct. The exhaust hole communicates with the inner cavity of the square ring tube. A connecting pipe communicating with the inner cavity of the square ring tube is fixedly connected to the surface of the square ring tube along a third direction. The end of the connecting pipe passes through the surface of the neck duct along a first direction and extends into the inner cavity of the neck duct. A suction pipe is slidably connected to the inside of the connecting pipe along a second direction. The suction pipe passes through the air regulating plate and is fixedly connected to the air regulating plate.

[0007] Preferably, one end of the spring is fixedly connected to the gas collecting hood, and the other end of the spring is fixedly connected to the support ring.

[0008] Preferably, a fixed plate is fixedly connected to the end of the square rod away from the air collection hood, a connecting rod is fixedly connected radially on the circumferential surface of the fixed plate, a linkage rod is fixedly connected to the side of the connecting rod near the air guide plate, an adjusting rod is hinged to the end of the linkage rod away from the connecting rod, and the end of the adjusting rod away from the linkage rod is hinged to the air guide plate.

[0009] Preferably, the projection of the cross along a third direction coincides with the two diagonals of the projection of the air outlet duct along a third direction.

[0010] Preferably, it also includes a cooling duct extending in a third direction, one end of which is fixedly installed on the surface of the air inlet duct in the third direction and connected to the air duct of the air inlet duct.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes the flow of cold air within the air duct assembly to create negative pressure in the neck duct, forcing the air intake mechanism's outlet end to draw air into the air duct assembly. This, in turn, draws in ambient air from the cabin into the air duct assembly, mixing it with the cold air. This rapidly brings the supply air temperature close to room temperature, avoiding the discomfort of direct cold air blowing on the body. Furthermore, the combined effects of air intake and suction promote airflow throughout the room, eliminating dead zones and creating a more uniform temperature and velocity field. During this process, the adjusting end of the adjusting mechanism controls the sliding of the air regulating plate within the neck duct, causing changes in the ventilation cross-section of the neck duct and reducing... The small neck duct's ventilation cross-section increases the air velocity and negative pressure within it, thus accelerating the air intake mechanism's air intake speed and increasing the proportion of air in the neck duct. This results in a supply air temperature closer to room temperature. Conversely, expanding the neck duct's ventilation cross-section reduces the air velocity and negative pressure, decreasing the air intake mechanism's air intake speed and further reducing the proportion of air in the neck duct. This leads to a lower supply air temperature and stepless control of the air supply, dynamically matching the room's real-time temperature to improve comfort and maximize energy savings.

[0012] 2. This invention, through the setting of the air guide plate, can guide the airflow entering the cabin. When the airflow speed in the air duct assembly is high, the airflow acts on the adaptive mechanism, causing the adaptive mechanism to change force, which in turn causes the moving end of the adaptive mechanism to move a large distance in the third direction. This causes the air guide plate to rotate around the support axis and deflect significantly, resulting in a large change in the tilt angle of the air guide plate. This causes the airflow direction to change outward, avoiding a strong feeling of cold air due to high cooling capacity and high wind speed, thus improving comfort. When the airflow speed in the air duct assembly is low, the moving end of the adaptive mechanism moves a small distance. At this time, the change in the tilt angle of the air guide plate is small, and the change in the airflow direction is small. The air guide plate has the effect of converging the airflow, ensuring that the airflow has sufficient range and penetration, preventing the cold air from sinking too early, and maintaining the temperature uniformity at the far end of the room.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-8A marine combined air distributor includes: an air duct assembly 100, including a neck duct 120 extending in a third direction; and an air regulating assembly 300, including an air inlet mechanism 310, an air regulating plate 320, and an adjusting mechanism 330. The air inlet end of the air inlet mechanism 310 is connected to the air duct assembly 100, and the air outlet end of the air inlet mechanism 310 is connected to the air regulating plate 320. The air regulating plate 320 is slidably connected in the neck duct 120 in a second direction. The fixed end of the adjusting mechanism 330 is disposed on the neck duct 120, and the adjusting end of the adjusting mechanism 330 moves in the second direction. The adjusting end of the adjusting mechanism 330 is connected to the air regulating plate 320 and is used to drive the air regulating plate 320 to slide in the second direction. The air guide assembly 400 includes an air guide plate 410 and an adaptive mechanism 420. The end of the air guide plate 410 is fixedly connected to a support shaft 411, which is rotatably connected to the air duct assembly 100. The fixed end of the adaptive mechanism 420 is connected to the air duct assembly 100, and the moving end of the adaptive mechanism 420 moves along a third direction. The moving end of the adaptive mechanism 420 is connected to the air guide plate 410 and is used to drive the air guide plate 410 to rotate. By setting up the air duct assembly 100, the core of which is the neck duct 120 extending in a third direction, the neck duct 120 acts as a Venturi constriction section, forming a convergent airflow channel within its inner cavity. This allows primary air entering from the upstream of the air duct assembly 100 to accelerate here, thereby generating negative pressure in the neck duct 120 region to draw in the return air from the cabin, completing the initial mixing of the cold air and the cabin air. At the same time, the neck duct 120 provides a guide mounting position for the downstream air regulating plate 320. The air intake mechanism 310, the air regulating plate 320, and the distance regulating mechanism 330 are jointly constructed. The air intake mechanism 310 is the air introduction channel in the cabin. The air intake end of the air intake mechanism 310 is connected to the cabin space. The air outlet end of the air intake mechanism 310 guides the airflow into the inner cavity of the neck duct 120, so that the airflow must pass through the throat region. The air regulating plate 320, as a variable cross-section component, slides and is limited in the neck duct 120 along the second direction. It is used to enlarge or reduce the throat region by changing the distance between the two air regulating plates 320. The flow area is adjusted to regulate the airflow velocity at the throat. The adjusting end of the adjusting mechanism 330 is used to drive the air regulating plate 320 to move stably. By setting the air guide assembly 400, which includes an air guide plate 410 and an adaptive mechanism 420, the air guide plate 410 serves as an airflow guiding element at the outlet of the air distributor. Its end is fixed with a support shaft 411. The support shaft 411 is rotatably connected to the outlet frame of the air duct assembly 100 through a shaft hole structure, so that the air guide plate 410 can rotate around the axis of the support shaft 411 to change the outlet tilt angle, thereby determining the long-distance wall jet and near-area large diffusion air supply. The fixed end of the adaptive mechanism 420 is set on the housing of the air duct assembly 100. The moving end of the adaptive mechanism 420 generates a linear displacement along the third axial direction and is linked with the air guide plate 410, thereby causing the air guide plate 410 to deflect. This is used to sense the change in airflow magnitude caused by the change in throat area in the neck pipe 120. The axial displacement of the moving end of the adaptive mechanism 420 is converted into the rotation angle of the air guide plate 410. Cold air circulates within the air duct assembly 100, causing the neck duct 120 to draw air into the air duct assembly 100 through the air intake mechanism 310. This, in turn, draws in cabin air into the air duct assembly 100, mixing it with the cold air. This rapidly brings the supply air temperature close to room temperature, avoiding the discomfort of direct cold air blowing on the body. Furthermore, the combined effects of air intake and suction promote airflow throughout the room, eliminating dead zones and creating a more uniform temperature and velocity field. During this process, the adjusting end of the adjusting mechanism 330 controls the sliding of the air regulating plate 320 within the neck duct 120, changing the ventilation cross-section of the neck duct 120 and reducing its size. With an increased ventilation cross-section of the neck duct 120, the air velocity within the neck duct 120 increases, the negative pressure within the neck duct 120 strengthens, and the air intake end of the air intake mechanism 310 draws air from the cabin at a higher speed, resulting in a larger proportion of cabin air within the neck duct 120 and a supply air temperature closer to room temperature. By expanding the ventilation cross-section of the neck duct 120, the air velocity within the neck duct 120 decreases, the negative pressure within the neck duct 120 weakens, and the air intake end of the air intake mechanism 310 draws air from the cabin at a lower speed, resulting in a smaller proportion of cabin air within the neck duct 120 and a lower supply air temperature. This achieves stepless control of the supply air status, dynamically matching the real-time room temperature, improving comfort and maximizing energy savings. By setting the air guide plate 410, the airflow entering the cabin can be guided. When the airflow speed in the air duct assembly 100 is high, the airflow acts on the adaptive mechanism 420, causing the adaptive mechanism 420 to change force. As a result, the moving end of the adaptive mechanism 420 moves a large distance in the third direction, causing the air guide plate 410 to rotate around the support shaft 411 and deflect significantly. This results in a large change in the tilt angle of the air guide plate 410, which in turn causes the airflow direction to change outward, avoiding a strong feeling of cold air due to high cooling capacity and high wind speed, thus improving comfort. When the airflow speed in the air duct assembly 100 is low, the moving end of the adaptive mechanism 420 moves a small distance. At this time, the change in the tilt angle of the air guide plate 410 is small, and the change in the airflow direction is small. The air guide plate 410 has the function of converging the airflow, ensuring that the airflow has sufficient range and penetration, preventing the cold air from sinking too early, and maintaining the temperature uniformity at the far end of the room.

[0017] In this embodiment, as a preferred option, the air duct assembly 100 further includes an air inlet duct 110 and an air outlet duct 130. The air inlet duct 110, the neck duct 120 and the air outlet duct 130 are arranged sequentially along a third direction. The projected areas of the neck duct 120, the air inlet duct 110 and the air outlet duct 130 along the third direction increase sequentially. The surface of the air inlet duct 110 along the third direction and the neck duct 120 are installed by bolts. The end of the neck duct 120 away from the air inlet duct 110 and the air outlet duct 130 are installed by bolts. A cross 140 is fixedly connected to the inner cavity of the air outlet duct 130. By setting up an inlet duct 110, which serves as the initial flow channel for primary air entering the cabin, the airflow is smoothly guided downstream. By setting up a neck duct 120, which serves as the core narrowing section for the Venturi effect, the airflow is accelerated and a negative pressure zone is formed. The two ends of the neck duct 120 are bolted to the inlet duct 110 and the outlet duct 130, respectively, forming a detachable complete airflow channel. By setting up an outlet duct 130, which serves as the diffusion and outlet section for the mixed airflow, its internal cross-sectional area is larger than that of the neck duct 120, which is used to reduce the airflow velocity and restore static pressure, making the air mixing more uniform. By setting up a cross 140 in the inner cavity of the outlet duct 130, which serves as a support and rectification structure, the air guide plate 410 is installed. In use, the airflow flows through the inlet duct 110, the neck duct 120 and the outlet duct 130 in sequence, completing the complete process of airflow introduction, acceleration, and diffusion output.

[0018] In this embodiment, as a preferred option, the air inlet mechanism 310 includes a square ring tube 311, which is fixedly sleeved on the outer surface of the air outlet duct 130. The square ring tube 311 has an exhaust hole 312 on its surface away from the air outlet duct 130. The exhaust hole 312 communicates with the inner cavity of the square ring tube 311. A connecting pipe 313 communicating with the inner cavity of the square ring tube 311 is fixedly connected to the surface of the square ring tube 311 along a third direction. The end of the connecting pipe 313 passes through the surface of the neck duct 120 along a first direction and extends to the inner cavity of the neck duct 120. A suction pipe 314 is slidably connected to the inside of the connecting pipe 313 along a second direction. The suction pipe 314 passes through the air regulating plate 320 and is fixedly connected to the air regulating plate 320. By setting up a square annular pipe 311, the square annular pipe 311 is located inside the cabin during the overall installation of the device. It is used to introduce ambient air from around the square annular pipe 311 into the system through exhaust holes 312 on its surface. A connecting pipe 313 serves as a transmission channel connecting the inner cavity of the square annular pipe 311 to the inner cavity of the neck duct 120, used to directionally transport the collected cabin air to the neck duct 120 area. A suction pipe 314 is provided, whose inlet end moves synchronously with the air regulating plate 320 to regulate airflow. When the plate 320 moves, the chamber formed between the connecting pipe 313 and the two air regulating plates 320 is connected. During operation, when the air regulating plate 320 moves along the second direction under the drive of the adjusting mechanism 330 to change the effective flow area of ​​the airflow in the neck pipe 120, the suction pipe 314 fixed on the air regulating plate 320 slides synchronously in the connecting pipe 313. When the airflow velocity and negative pressure in the neck pipe 120 change, the exhaust hole 312 can draw in the surrounding air, realizing the mixing between the primary air intake and the introduced air.

[0019] In this embodiment, as a preferred solution, the adjusting mechanism 330 includes a connecting rod 331, which is slidably connected to the neck pipe 120 along the second direction. The end of the connecting rod 331 located in the neck pipe 120 is fixedly connected to the air regulating plate 320. The other end of the connecting rod 331 is fixedly connected to a sliding plate 332, which is slidably connected to the neck pipe 120. A guide groove 333 is opened on the surface of the sliding plate 332 away from the neck pipe 120. A support plate 334 is fixedly connected to the surface of the neck pipe 120 along the first direction. A cylinder 335 is fixedly installed on the surface of the support plate 334 along the third direction. The cylinder rod of the cylinder 335 passes through the surface of the support plate 334 and is slidably connected to the support plate 334. A connecting plate 336 is fixedly connected to the surface of the cylinder rod of the cylinder 335 along the third direction. A sliding pin 337 is fixedly connected to the surface of the connecting plate 336 near the neck pipe 120. The sliding pin 337 is slidably connected in the guide groove 333. By setting a connecting rod 331 as a transmission component to move the air regulating plate 320, the linear displacement of the driving end of the adjusting mechanism 330 is transmitted to the air regulating plate 320, realizing the movement of the air regulating plate 320 along the second direction. By setting a sliding plate 332 as a support and guide base for the connecting rod 331, it is used to support the connecting rod 331 and ensure its stable movement along the second direction, and to seal the groove in the neck pipe 120 for sliding the connecting rod 331 to prevent air leakage. By setting a guide groove 333 and a sliding pin 337, the guide groove 333 and the sliding pin 337 cooperate to convert the movement of the driving end of the adjusting mechanism 330 into the movement of the sliding plate 332 along the second direction. By setting a support plate 334, it is used to provide stable support for the cylinder 335. It is fixed on the support plate 334 as a drive source to provide linear power. By setting the connecting plate 336, the connecting plate 336 is fixedly connected to the cylinder rod of the cylinder 335. As an extension component of the cylinder rod, it is used to transmit the linear motion of the cylinder rod to the sliding pin 337. When the cylinder 335 is started, when its cylinder rod extends and retracts in the third direction, it drives the connecting plate 336 and the sliding pin 337 to move synchronously. Since the sliding pin 337 is slidably connected in the guide groove 333 of the slide plate 332, the horizontal movement of the sliding pin 337 will generate a component force perpendicular to its direction of movement along the inclined trajectory of the guide groove 333. The component force pushes the slide plate 332 to slide in the second direction. The slide plate 332 drives the air regulating plate 320 to move through the connecting rod 331, thereby driving the air regulating plate 320 to move in the neck pipe 120 to realize the adjustment of the throat flow area.

[0020] In this embodiment, as a preferred option, the adaptive mechanism 420 includes a support rod 421. The support rod 421 and the inner surface of the air outlet duct 130 are connected by screws. A support ring 422 is fixedly connected to the end of the support rod 421 away from the inner surface of the air outlet duct 130. A square rod 423 is slidably connected inside the support ring 422 along the third direction. An air collection hood 424 is fixedly connected to the surface of the square rod 423 along the third direction. A spring 425 extending along the third direction is sleeved on the outer side of the square rod 423. A support rod 421 is connected to the inner surface of the air outlet duct 130 by screws, serving as the mounting base for the entire adaptive mechanism 420. A support ring 422 is fixedly connected to the end of the support rod 421, allowing the square rod 423 to slide linearly only along a third direction while restricting its rotation. The square rod 423 converts aerodynamic force into linear displacement and transmits it to downstream linkage components. An air collection hood 424 serves as a pressure sensing and collection component, receiving changes in airflow pressure within the air outlet duct 130 and converting the pressure into an axial force acting on the square rod 423. A spring 425, sleeved on the outside of the square rod 423 and extending along a third direction, acts as a reset and balancing element for the system, applying a preset elastic force to the air collection hood 424 to drive the square rod 423 and the air collection hood 424 to reset when the airflow pressure decreases.

[0021] In this embodiment, as a preferred option, one end of the spring 425 is fixedly connected to the gas collection hood 424, and the other end of the spring 425 is fixedly connected to the support ring 422. By setting the spring 425, the gas collection hood 424 can automatically reset.

[0022] In this embodiment, as a preferred option, a fixed plate 426 is fixedly connected to one end of the square rod 423 away from the air collection hood 424. A connecting rod 427 is fixedly connected radially on the circumferential surface of the fixed plate 426. A linkage rod 428 is fixedly connected to one side of the connecting rod 427 near the air guide plate 410. An adjusting rod 429 is hinged to one end of the linkage rod 428 away from the connecting rod 427. The end of the adjusting rod 429 away from the linkage rod 428 is hinged to the air guide plate 410. A fixed plate 426 is provided to increase the circumferential area for mounting multiple connecting rods 427. The connecting rods 427 extend the movement of the fixed plate 426. A linkage rod 428 is fixedly connected to the side of the connecting rod 427 near the air guide plate 410 to transmit the movement of the connecting rod 427 in a third direction. An adjusting rod 429 is provided, with one end hinged to the linkage rod 428 and the other end hinged to the air guide plate 410, to adjust the movement of the linkage rod 428 in a third direction. The motion is converted into the rotational motion of the air guide plate 410 around the support shaft 411. When the adaptive mechanism 420 senses the change in airflow and drives the square rod 423 to move along the third direction, the fixed plate 426 moves synchronously. The linear displacement of the fixed plate 426 along the third direction is converted into the movement of the linkage rod 428 along the third direction through the connecting rod 427 that is radially fixed to it, and is received by the adjusting rod 429, so that the adjusting rod 429 deflects and pushes the air guide plate 410, causing the air guide plate 410 to generate a corresponding angular deflection around the support shaft 411.

[0023] In this embodiment, as a preferred option, the projection of the cross 140 along the third direction coincides with the two diagonals of the projection of the air outlet duct 130 along the third direction. By setting the cross 140, it serves as a support member inside the air outlet duct 130, providing a stable support for the air guide plate 410.

[0024] In this embodiment, as a preferred option, a cooling pipe 200 extending along a third direction is also included. One end of the cooling pipe 200 is fixedly installed on the surface of the air inlet duct 110 along the third direction and is connected to the air duct of the air inlet duct 110. By setting the cooling pipe 200 extending along the third direction, it serves as a dedicated input channel for the external air conditioning cold source, and is used to introduce the centrally processed low-temperature primary air into the front air duct of the air distributor.

[0025] The specific implementation process of this invention is as follows: During device installation, the air outlet duct 130 and the square ring pipe 311 are located inside the cabin. When adjusting the temperature inside the cabin, the cooling fan is started to draw air into the air inlet duct 110 through the cooling pipe 200. The airflow flows through the air inlet duct 110, through the neck duct 120 and the air outlet duct 130, and is then guided by the air guide plate 410 before being discharged. When the airflow enters the neck duct 120 from the air inlet duct 110, since the projected area of ​​the neck duct 120 along the third direction is smaller than the projected area of ​​the air inlet duct 110 along the third direction, the airflow velocity in the neck duct 120 increases, thereby creating a negative pressure in the neck duct 120. At this time, the neck duct 120 draws air from the connecting pipe 313 through the suction pipe 314. Air is drawn into the square ring pipe 311 by the connecting pipe 313, which in turn draws air from the cabin through the exhaust hole 312. The air in the cabin is drawn into the neck pipe 120, mixed, and then discharged from the exhaust pipe 130. Cold air circulates through the air duct assembly 100, which in turn draws air into the air duct assembly 100 through the exhaust end of the air intake mechanism 310. The air intake end of the air intake mechanism 310 draws air from the cabin into the air duct assembly 100 and mixes it with the cold air, so that the supply air temperature quickly approaches room temperature, avoiding the discomfort of cold air blowing directly on the human body. Under the dual action of air intake and suction, the air in the entire room is circulated, eliminating dead corners and making the temperature and velocity fields more uniform. When the initial room temperature and the temperature difference between the room temperature and the cold air discharged by the refrigeration fan are large, cylinder 335 is activated. Cylinder 335 drives the cylinder rod to extend, which in turn moves the connecting plate 336 along a third direction. The connecting plate 336 then moves the sliding pin 337 along a third direction. The sliding pin 337 slides within the guide groove 333, causing the slide plate 332 to move along a second direction. The slide plate 332 then moves the connecting rod 331 along a second direction, which in turn moves the air regulating plate 320 along a second direction. This changes the distance between the two air regulating plates 320, thus altering the projected area of ​​the flow channel formed by the air regulating plate 320 and the neck duct 120 along a third direction. When the distance between the two air regulating plates 320 decreases, the projected area of ​​the flow channel formed by the neck duct 120 and the air regulating plate 320 along a third direction decreases, increasing the air velocity within the neck duct 120 and strengthening the negative pressure within the neck duct 120. This enhances the suction force of the suction pipe 314, which in turn enhances the suction force within the connecting pipe 313 and the square ring pipe 311. This, in turn, increases the speed at which the exhaust port 312 draws air from the cabin, resulting in a larger proportion of cabin air within the neck duct 120 and a supply air temperature closer to room temperature. When the distance between the two air regulating plates 320 increases, the projected area of ​​the flow channel formed by the neck duct 120 and the air regulating plate 320 along the third direction increases, reducing the wind speed and negative pressure within the neck duct 120. This, in turn, weakens the suction force of the suction pipe 314, which in turn weakens the suction force within the connecting pipe 313 and the square ring pipe 311. This, in turn, reduces the speed at which the exhaust port 312 draws air from the cabin, resulting in a smaller proportion of cabin air within the neck duct 120 and a lower supply air temperature. This achieves stepless control of the supply air status, dynamically matching the real-time room temperature, improving comfort, and maximizing energy savings. When the airflow velocity within the duct assembly 100 increases, the air pressure on the air collecting hood 424 increases, causing it to move a greater distance in the third direction. This movement compresses the spring 425, which in turn moves the square rod 423. The square rod 423 then moves the fixed plate 426, which in turn moves the connecting rod 427. The connecting rod 427 then moves the linkage rod 428, causing the linkage rod 428 to deflect. This deflects the air guide plate 410. The greater the air pressure on the air collecting hood 424, the greater the deflection of the air guide plate under the linkage. The larger the deflection angle of 410, the greater the wind pressure, and the greater the change in the tilt angle of the air guide plate 410. This causes the airflow direction to change outward, avoiding a strong feeling of cold air due to large cooling capacity and high wind speed, thus improving comfort. When the airflow speed in the air duct assembly 100 is low, the movement stroke of the air collection hood 424 is small. At this time, the change in the tilt angle of the air guide plate 410 is small, and the change in the airflow direction is small. The air guide plate 410 has the function of converging the airflow, ensuring that the airflow has sufficient range and penetration, preventing the cold air from sinking too early, and maintaining the temperature uniformity at the far end of the room.
