[0002] Air conditioning and ventilation units are an indispensable part of modern buildings. They ensure the circulation, freshness and comfort of indoor air through different equipment and systems. The fresh air fan draws in fresh air from the outside and purifies the air through a filtration system. The purified air is sent into the room through the air supply duct. At the same time, the dirty air in the room is discharged from the room through the return air duct. The system automatically adjusts the amount of fresh air introduced and the air supply speed according to the indoor and outdoor environmental conditions to maintain the comfort and freshness of the indoor air.

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention incorporates a ventilation duct assembly. Condensed water enters the ventilation duct along with fresh air from the air conditioner. Due to its own gravity, the condensed water flows to the bottom of the ventilation duct. The air guide plate assembly is provided to reduce the diameter of the fresh air passage and is located at the top of the ventilation duct. Under the action of inertia and gravity, the condensed water flows into the interior through the water inlet holes of the inclined plate. Driven by the gentle wind, a drainage assembly is provided at one end of the horizontal plate. The fan plate rotates with the wind. The fan plate is provided with a water inlet groove, and a water outlet guide vane is provided within the intermediate shaft. The fan plate intercepts the condensed water into the water inlet groove and transmits it to the air conditioner cooling water tank through a pipe, thereby improving water resource utilization and environmental protection. The intermediate shaft rotates, driving the first gear to rotate. The first track is equipped with a brush. As it rotates, it cleans the inner wall of the duct shell, removing water stains caused by the condensed water, preventing it from dripping from the air outlet and solving the problem of items near the air outlet getting soaked.

[0016] 2. This invention incorporates a drying assembly, which is pinned to the wheel assembly via an intermediate shaft, driving the wheel assembly to rotate. This friction between the wheel assembly and the friction disk generates heat. When the ventilation duct stops delivering fresh air, the heat-generating blocking plate expands and opens, allowing the hot air to pass through the air pipe and air inlet and transfer heat to the ventilation duct. This dries the duct's inner wall, preventing moisture and mold growth, thereby improving the safety of the ventilation duct.

[0017] 3. This invention incorporates a return air assembly. When fresh air flows through the ventilation duct, it rotates the windshield. The second track then drives the spring around the rotating rod. When the ventilation duct stops delivering fresh air, the spring releases its elastic potential energy, rotating the disc. The disc connects to the fan blades, causing the blades to rotate and generate return air, which flows into the ventilation duct, improving the dryness of the duct. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] What needs to be specifically explained in this embodiment is that the condensed water enters the tube shell assembly 101 together with the fresh air from the air conditioner. Due to the gravity of the condensed water itself, the condensed water will flow at the bottom of the tube shell assembly 101. By setting up the wind guide plate assembly 102, the channel diameter of the fresh air is reduced and located at the upper part of the tube shell assembly 101. Under the action of inertia and gravity, the condensed water flows into the interior from the water inlet hole 1022 of the inclined plate 1021. With the slight wind flow, one end of the horizontal plate 1023 is provided with a drainage assembly 103, and the fan plate 1033 rotates with the wind. The fan plate 1033 rotates with the wind. A water inlet trough 1034 is provided and a water outlet guide 1038 is provided inside the intermediate shaft 1031.

The first crawler 1044 is provided with a brush 1046, which cleans the inner wall of the side of the pipe shell 1011 when rotating, so that the water stains caused by the condensed water can be cleaned, which is beneficial to avoid dripping from the air outlet and solves the problem of objects near the air outlet being soaked.

[0045] Reference Figure 10 The drying component 2 includes a wheel assembly 201, a friction disc 202 is rotatably sleeved on the front of the wheel assembly 201, a connecting rod 203 is fixedly connected to the front of the friction disc 202, one end of the connecting rod 203 is fixedly connected to a sealing shell 204, one side of the sealing shell 204 is fixedly connected to one side of the tube shell assembly 101, the top pipe of the sealing shell 204 is connected to the air pipe 205, the top pipe of the air pipe 205 is connected to the air intake shell 206, and one side of the air intake shell 206 is fixedly connected to one side of the tube shell assembly 101.

[0046] Reference Figure 11The wheel assembly 201 includes a turntable 2011, a friction groove 2012 is provided on one side of the turntable 2011, a connecting shaft 2013 is fixedly connected to the other side of the turntable 2011, and a pin 2014 is provided on the side of one end of the connecting shaft 2013.

[0047] What needs to be specifically explained in this embodiment is that the connecting shaft 2013 is connected to the connecting groove 1035, and is pinned to the turning wheel assembly 201 through the intermediate shaft 1031, driving the turning wheel assembly 201 to rotate, so that the turning wheel assembly 201 and the friction disk 202 rotate and rub to generate heat. When the ventilation duct stops delivering fresh air, the blocking piece 1014 opens due to heat expansion, allowing the hot air to transfer heat to the ventilation duct through the air pipe 205 and the air inlet 1012, drying the inner wall of the ventilation duct to prevent it from being damp and breeding mold, thereby improving the safety of the ventilation duct.

[0048] Reference Figure 12 The return air component 3 includes a protective shell 301, an air outlet window 302 is provided on the back of the protective shell 301, a movable groove 303 is provided on the bottom of the protective shell 301, a short roller 304 is rotatably connected to the inner side of the movable groove 303, a roller 305 is fixedly sleeved on the side of the short roller 304, four wind deflectors 306 are fixedly connected to the side of the roller 305, one end of the short roller 304 is movably sleeved with a second track 307, the top of the second track 307 is movably sleeved with a long roller 308, both ends of the long roller 308 are rotatably connected to the inner wall of the protective shell 301, a third gear 309 is fixedly sleeved in the middle of the long roller 308, and the side of the third gear 309 is meshed with a fan assembly 310.

[0049] Reference Figure 13 The fan assembly 310 includes a rotating rod 3101, one end of which is fixedly connected to a fourth gear 3102, and the other end of which is fixedly connected to a spring 3103.

A stop block 3105 is provided on the back of the top of the sleeve rod 3104 and the two are not connected. One side of the disc 3106 is fixedly connected to a fan shaft 3108, and one end of the fan shaft 3108 is fixedly connected to a fan blade 3107. The side of the fan shaft 3108 is rotatably sleeved with a ring 3109, and the top of the ring 3109 is fixedly connected to the inner side of the top of the shell and tube assembly 101.

[0050] What needs to be specifically explained in this embodiment is that when the fresh air passes through the shell and tube assembly 101, the wind shield 306 is blown to rotate, and the transmission effect of the second crawler 307 winds the spring 3103 tightly on the rotating rod 3101. When the shell and tube assembly 101 stops delivering fresh air, the spring 3103 releases its elastic potential energy and rotates the disc 3106. The disc 3106 is connected to the fan blades 3107, so that the fan blades 3107 rotate to generate return air, which flows into the shell and tube assembly 101, which is beneficial to improving the dryness of the ventilation duct.

[0051] The working principle of the present invention is as follows: condensed water enters the tube shell assembly 101 together with the fresh air from the air conditioner. Due to the gravity of the condensed water itself, the condensed water will flow at the bottom of the tube shell assembly 101. By setting up the wind guide plate assembly 102, the channel diameter of the fresh air is reduced and located at the upper part of the tube shell assembly 101. Under the action of inertia and gravity, the condensed water flows into the interior from the water inlet hole 1022 of the inclined plate 1021. With the slight wind flow, one end of the horizontal plate 1023 is provided with a drainage assembly 103, and the fan plate 1033 rotates with the wind. The fan plate 1033 is provided with an inlet hole 1022. The water tank 1034 and the intermediate shaft 1031 are provided with a water outlet guide 1038, and the fan plate 1033 intercepts the condensed water into the water tank 1034 and transmits it to the air-conditioning cooling water tank through the pipeline, thereby improving the utilization rate of water resources and environmental protection. The intermediate shaft 1031 rotates, driving the first gear 1032 to rotate. The first crawler 1044 is provided with a brush 1046, which cleans the inner wall of the side of the pipe shell 1011 when rotating, so that the water stains caused by the condensed water can be cleaned, which is conducive to avoiding dripping from the air outlet and solving the problem of objects near the air outlet being soaked.

[0052] The connecting shaft 2013 is connected to the connecting groove 1035, and is pinned to the turning wheel assembly 201 through the intermediate shaft 1031, driving the turning wheel assembly 201 to rotate, so that the turning wheel assembly 201 and the friction disk 202 rotate and rub to generate heat. When the ventilation duct stops delivering fresh air, the blocking piece 1014 expands due to the heat and opens, allowing the hot air to pass through the air pipe 205 and the air inlet 1012 to transfer the heat to the ventilation duct, drying the inner wall of the ventilation duct to prevent it from being damp and breeding mold, thereby improving the ventilation duct. To ensure the safety of the duct, when the fresh air passes through the tube shell assembly 101, the wind shield 306 is blown to rotate, and then the spring 3103 is tightly wound on the rotating rod 3101 through the transmission effect of the second crawler 307. When the tube shell assembly 101 stops delivering fresh air, the spring 3103 releases its elastic potential energy and rotates the disc 3106. The disc 3106 is connected to the fan blades 3107, so that the fan blades 3107 rotate to generate return air, which flows into the tube shell assembly 101, which is beneficial to improving the dryness of the ventilation duct.
