The rotation range of the first wind vanes is 0° to 90°. The rotation range of the second wind vanes is -90° to 0°.

[0009] In one embodiment of this utility model, two connecting plates are fixedly connected to one side of the rack, two fixing plates are fixedly connected to both sides of the housing, and two sliding rods are fixedly connected between the two fixing plates on the same side, and the connecting plates slide on the sliding rods.

[0010] In one embodiment of this utility model, a device body is installed inside the housing, a heat dissipation plate is provided on the rear side wall of the housing, a dustproof plate is provided on the outer side of the heat dissipation plate, and the four corners of the dustproof plate are fixed to the housing by fastening bolts; two fans are installed on the inner side wall of the heat dissipation plate by a mounting bracket.

[0011] In one embodiment of this utility model, a water tank is fixedly connected to the outer wall of the housing, and a water outlet pipe is connected to the water tank. One end of the water outlet pipe is connected to a first branch pipe, and one end of the first branch pipe is connected to the housing. A second branch pipe is connected to the upper part of the water outlet pipe, and one end of the second branch pipe is connected to the housing. One end of the first branch pipe and the second branch pipe are respectively aligned with the central axis of the two fans.

[0017] This utility model discloses a layered air supply HVAC device. By setting a first air outlet plate and a second air outlet plate, it is used to meet different air outlet directions. The drive mechanism drives the first air outlet plate to synchronously change the air outlet direction, forming a first air supply tilt angle; the drive mechanism drives the second air outlet plate to synchronously change the air outlet direction, forming a second air supply tilt angle. When the air supply tilt angle changes, the corresponding electric push rod needs to be activated.

[0018] The layered air supply HVAC device described in this utility model, by setting a limiting block and a spring, requires pushing the fixing frame to one side when replacing the dust screen. The fixing frame compresses the spring, causing the limiting block to move away from the push plate, thus releasing the fixation on the push plate. The push plate can then be pulled out to remove the dust screen. After cleaning the dust screen, when it needs to be installed, the fixing frame is pushed to one side, compressing the spring. The spring compresses the limiting block to one side, thus pushing the push plate inward. The dust screen is inserted into the housing. Loosening the fixing frame, under the action of the spring, the limiting block is inserted into the push plate, thus fixing the dust screen. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1-6 As shown, this utility model discloses a layered air supply HVAC device, comprising a housing 1. Three first airflow vanes 2 are rotatably connected to the front side wall of the housing 1 via rotating rods. Three second airflow vanes 3 are located above the first airflow vanes 2, and each of the second airflow vanes 3 is rotatably connected to the housing 1 via rotating rods. A driving mechanism is provided on one side of each of the first airflow vanes 2 and the second airflow vanes 3. Two driving mechanisms are respectively located on both sides of the housing 1. Each driving mechanism includes an electric push rod 4 fixed to the side wall of the housing 1. A rack 41 is fixed to the output end of each electric push rod 4, and a gear 42 is fixed to one end of each rotating rod. The gears 42 mesh with the rack 41 on the same side. The rotation range of the first airflow vanes 2 is 0° to 90°; the rotation range of the second airflow vanes 3 is -90° to 0°.

[0029] During operation, a first airflow vane 2 and a second airflow vane 3 are set up to meet different airflow directions. The drive mechanism drives the first airflow vane to synchronously change the airflow direction, forming a first airflow tilt angle; the drive mechanism drives the second airflow vane to synchronously change the airflow direction, forming a second airflow tilt angle. When the airflow tilt angle changes, the corresponding electric push rod 4 needs to be activated. The output end of the electric push rod 4 drives the rack 41 to move, the rack 41 drives the gear 42 to rotate, the gear 42 drives the rotating rod to rotate, and the rotating rod drives the connected first and second airflow vanes to rotate. The two sets of airflow tilt angles can be constantly changing or fixed. The two airflow tilt angles can meet the airflow in two directions, making the entire airflow space more layered and giving people a better experience.

[0030] Furthermore, such as Figure 2 As shown, two connecting plates 43 are fixedly connected to one side of the rack 41, and two fixing plates 44 are fixedly connected to both sides of the housing 1. Two sliding rods 45 are fixedly connected between the two fixing plates 44 on the same side, and the connecting plates 43 slide on the sliding rods 45.

[0031] During operation, the rack 41 moves, driving the connecting plate 43 to move. The connecting plate 43 slides on the slide rod 45, which limits the movement of the connecting plate 43 and the rack 41 in the vertical direction.

[0032] Furthermore, such as Figure 3 As shown, the housing 1 houses the equipment body 13, the rear side wall of the housing 1 is provided with a heat dissipation plate 15, the outer side of the heat dissipation plate 15 is provided with a dustproof plate 16, and the four corners of the dustproof plate 16 are fixed to the housing 1 by fastening bolts 11; the inner side wall of the heat dissipation plate 15 is equipped with two fans 14 by mounting brackets.

[0033] During operation, the equipment body 13 is used for heating, ventilation and air conditioning operation of HVAC, the heat dissipation plate 15 is used to facilitate heat dissipation of the equipment body 13, the dustproof plate 16 is used to reduce dust entering the housing 1, the fastening bolts 11 are used to facilitate the replacement of the dustproof plate 16, and the fan 14 is used for air supply of HVAC.

[0034] Furthermore, such as Figure 3As shown, a water tank 63 is fixedly connected to the outer wall of the housing 1, and a water outlet pipe 6 is connected to the water tank 63. One end of the water outlet pipe 6 is connected to a first branch pipe 61, and one end of the first branch pipe 61 is connected to the housing 1. A second branch pipe 62 is connected to the upper part of the water outlet pipe 6, and one end of the second branch pipe 62 is connected to the housing 1. One end of the first branch pipe 61 and the second branch pipe 62 are respectively aligned with the central axis of the two fans 14. A miniature water pump 64 is fixedly connected to the water tank 63, and one end of the water outlet pipe 6 is installed on the miniature water pump 64.

[0035] When adjusting the humidity of the air during operation, the micro water pump 64 needs to be turned on. The micro water pump 64 delivers water from the water tank 63 to the water outlet pipe 6. The water is then discharged through the water outlet pipe 6 via the first branch pipe 61 and the second branch pipe 62. The water discharged from the first branch pipe 61 and the second branch pipe 62 drips downwards under the action of gravity. During the dripping process, the water droplets are atomized and sprayed out by the fan 14.

[0036] Furthermore, such as Figure 3 As shown, a collection groove 65 is fixedly connected to the bottom inner wall of the housing 1, and a drain pipe 66 is connected to one side of the collection groove 65. One end of the drain pipe 66 extends to the outside of the housing 1.

[0037] During operation, some water is not atomized and sprayed out, but drips under the action of gravity and eventually falls into the collection tank 65 and is discharged through the drain pipe 66.

[0038] Furthermore, such as Figure 3 As shown, two support columns 67 are fixedly connected to the bottom inner wall of the collection tank 65. The support columns 67 are respectively located below the first branch pipe 61 and the second branch pipe 62. Three diversion plates 68 are fixedly connected to each support column 67, and the three diversion plates 68 on the same side are staggered.

[0039] During operation, in order to reduce the falling speed of the water, a diversion plate 68 is set up. Under the action of the diversion plate 68, the water drips slowly, reducing water waste.

[0040] Furthermore, such as Figures 4 to 6 As shown, a dustproof net 5 is slidably connected inside the housing 1. Three push plates 51 are fixedly connected to the bottom of the dustproof net 5. Two limiting blocks 54 are inserted into each of the push plates 51. A fixing frame 52 is fixedly connected to one side of each of the two limiting blocks 54. Three sliding grooves are opened at the bottom of the housing 1. The fixing frame 52 is slidably connected to the sliding groove. Two springs 53 are fixedly connected to the side wall of each sliding groove. One end of each spring 53 is fixedly connected to the fixing frame 52.

[0041] When replacing the dustproof net 5 during operation, the fixing bracket 52 needs to be pushed to one side. The fixing bracket 52 compresses the spring 53, and the spring 53 is compressed. The limiting block 54 moves away from the push plate 51, releasing the fixation on the push plate 51. The push plate 51 can then be pulled out to remove the dustproof net 5. After cleaning the dustproof net 5, when it needs to be installed, the fixing bracket 52 is pushed to one side. The fixing bracket 52 compresses the spring 53, and the spring 53 is compressed. The limiting block 54 moves to one side, which pushes the push plate 51 inward. The dustproof net 5 is inserted into the housing 1. The fixing bracket 52 is then released. Under the action of the spring 53, the limiting block 54 is inserted into the push plate 51, thus fixing the dustproof net 5.

[0042] Furthermore, such as Figure 4 As shown, a humidity sensor 12 is fixedly attached to the side wall of the housing 1, and the humidity sensor 12 is electrically connected to the micro water pump 64.

[0043] During operation, the humidity sensor 12 monitors the ambient humidity. When the ambient humidity is lower than the set value, the humidity sensor 12 controls the micro water pump 64 to start via an electrical signal.

[0044] Working principle: By setting up a first air outlet plate 2 and a second air outlet plate 3 to meet different air outlet directions, the drive mechanism drives the first air outlet plate to synchronously change the air outlet direction, forming a first air supply tilt angle; the drive mechanism drives the second air outlet plate to synchronously change the air outlet direction, forming a second air supply tilt angle; when the air supply tilt angle changes, the corresponding electric push rod 4 needs to be activated. The output end of the electric push rod 4 drives the rack 41 to move, the rack 41 drives the gear 42 to rotate, the gear 42 drives the rotating rod to rotate, and the rotating rod drives the connected first air outlet plate and second air outlet plate to rotate. The two sets of air supply tilt angles can always be changing or can be fixed. The two air supply tilt angles can meet the air supply in two directions, making the entire air supply space more layered and giving people a better experience.

[0045] The equipment body 13 is used for heating, ventilation and air conditioning operation of HVAC. The heat dissipation plate 15 is provided to facilitate heat dissipation of the equipment body 13. The dustproof plate 16 is provided to reduce dust entering the interior of the housing 1. The fastening bolts 11 are provided to facilitate the replacement of the dustproof plate 16. The fan 14 is provided for air supply of HVAC.

[0046] When adjusting the humidity of the air, the micro water pump 64 needs to be turned on. The micro water pump 64 delivers water from the water tank 63 to the water outlet pipe 6. The water is then discharged through the first branch pipe 61 and the second branch pipe 62. The water discharged from the first branch pipe 61 and the second branch pipe 62 drips downwards under the action of gravity. During the dripping process, the water droplets are atomized and sprayed out by the fan 14. By setting up the diversion plate 68, the water drips slowly under the action of the diversion plate 68, reducing water waste. Some water is not atomized and sprayed out, but drips under the action of gravity and finally falls into the collection tank 65 and is discharged through the drain pipe 66.

[0047] When replacing the dustproof net 5, the fixing bracket 52 needs to be pushed to one side. The fixing bracket 52 compresses the spring 53, and the spring 53 is compressed. The limiting block 54 moves away from the push plate 51, releasing the fixation on the push plate 51. The push plate 51 can then be pulled out to remove the dustproof net 5. After cleaning the dustproof net 5, when it needs to be installed, the fixing bracket 52 is pushed to one side. The fixing bracket 52 compresses the spring 53, and the spring 53 is compressed. The limiting block 54 moves to one side, which pushes the push plate 51 inward. The dustproof net 5 is inserted into the housing 1. The fixing bracket 52 is then released. Under the action of the spring 53, the limiting block 54 is inserted into the push plate 51, thus fixing the dustproof net 5.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
