Description

Technical Field

[0001] This application relates to the field of air treatment technology, and in particular to an air treatment device. Background Technology

[0002] Various air handling equipment on the market, such as heaters, air purifiers, humidifiers, and water fans, are equipped with air outlet devices to change the direction of airflow. These outlet devices consist of a louvered frame and several louvers mounted on the frame. These louvers are spaced apart in a certain direction, forming airflow channels between adjacent louvers. In existing air outlet devices, each airflow channel between the louvers guides the airflow in the same direction, resulting in a narrow airflow range for the air handling equipment. Summary of the Invention

[0003] Therefore, it is necessary to provide an air handling device that improves upon the aforementioned shortcomings, addressing the issue of narrow air outlet range in existing air handling devices.

[0004] An air handling unit, comprising:

[0005] The device comprises: a base; a body with a mounting opening; and an air outlet assembly fitted into the mounting opening. The air outlet assembly includes: a louvered frame surrounding an air outlet, the louvered frame having an air inlet side and an air outlet side arranged opposite each other along a first direction, the air outlet connecting the air inlet side and the air outlet side; and a plurality of louvers rotatably mounted on the louvered frame, the plurality of louvers being spaced apart along a second direction perpendicular to the first direction; and a drive assembly including a power source and a pivot shaft driven by the power source to reciprocate at least along the second direction, the pivot shaft being disposed on the air inlet side, the louvers being rotatably connected to the pivot shaft to rotate synchronously under the drive of the pivot shaft, wherein each louver includes an air outlet side facing the air outlet side, the projection of each air outlet side in the second direction being an arc protruding towards the air outlet side; and the envelope surface of all air outlet sides being an arc protruding towards the air outlet side.

[0006] In one embodiment, the louver frame includes two sides arranged opposite each other in a third direction perpendicular to the first and second directions. Each side is provided with a first connecting hole evenly distributed for each louver. The louver includes an installation area at both ends and an air guiding area between the installation areas. A first rotating shaft extending in a third direction is provided in the installation area. The first rotating shaft is rotatably inserted into the corresponding first connecting hole. The line connecting the plurality of first connecting holes at least in the middle of either side of the louver frame is an arc shape convex toward the air outlet side.

[0007] In one embodiment, the air guide area of ​​at least a portion of the louvers also includes an air inlet side on the opposite side of the air outlet side, the air inlet side being an arc shape convex toward the air outlet side.

[0008] In one embodiment, the width of the air guide zone of the same louver is substantially equal.

[0009] In one embodiment, the distance between adjacent louvers is between 10 mm and 13 mm; the width of the air guide zone is between 14 mm and 16 mm; and the rotation angle of the louvers is between 50 degrees and 130 degrees with reference to the second direction.

[0010] In one embodiment, the width of the air guide zone of each louver is equal to that of the others.

[0011] In one embodiment, each side of the louvered frame also has a plurality of guide grooves, one end of each guide groove is connected to a first connecting hole, and the other end is disposed through the air outlet side in a direction parallel to the first direction; the depth of the guide groove is less than the depth of the first connecting hole.

[0012] In one embodiment, the louvered frame further includes two top edges disposed opposite each other in a second direction, the top edges being connected to the corresponding side edges by a connecting portion; the outer edge of the connecting portion forms an arc transition between the top edges and the corresponding side edges.

[0013] In one embodiment, the inner edge of the connecting portion is formed by a series of steps connected in sequence.

[0014] In one embodiment, at least a portion of the step has a first connecting hole formed on the step side along the second direction.

[0015] In one embodiment, a second pivot is provided in the mounting area of ​​each louver, offset from the first pivot; a plurality of second connecting holes are provided on the pivot shaft, and the second pivot is rotatably inserted into the corresponding second connecting hole.

[0016] In one embodiment, each louver has a mounting area with a widened portion extending toward the air inlet side, and a second pivot is disposed on the widened portion.

[0017] In one embodiment, the pivot shaft includes a first connecting rod extending in a second direction, and at least a portion of the second connecting hole is formed on the first connecting rod.

[0018] In one embodiment, the first connecting rod is adjacent to one side of the louver frame and its end is formed in an arc-shaped bend that matches the connecting portion.

[0019] In one embodiment, the pivot shaft further includes a second connecting rod extending in a second direction, the second connecting rod being spaced apart from the first connecting rod in a third direction and moving synchronously, and at least a portion of the second connecting hole being disposed on the second connecting rod.

[0020] In one embodiment, the first connecting rod and the second connecting rod are connected end to end to form a frame.

[0021] In one embodiment, the second connecting rod is disposed at the center of the louver frame; the second pivots of the first and last louvers in the second direction are rotatably inserted into the second connecting holes on the second connecting rod; the second pivots of the remaining louvers are rotatably inserted into the second connecting holes on the first connecting rod.

[0022] In one embodiment, the line connecting the plurality of second connecting holes on the first connecting rod is in the same arc shape as the line connecting the first connecting holes.

[0023] In one embodiment, a support strip is provided within the louvered frame, which is arranged compliantly and at intervals between two sides; one of the two sides and the support strip limit the pivot shaft from both sides, so that the pivot shaft moves in a second direction.

[0024] In one embodiment, the first connecting rod and the second connecting rod are located behind the louver frame, and the first connecting rod is covered by one of the two sides, while the second connecting rod is covered by the support strip.

[0025] In one embodiment, the frame further includes a plurality of internal support rods spaced apart, each internal support rod being connected to a second connecting rod and a first connecting rod.

[0026] In one embodiment, each inner support rod and each louver are aligned so that the inner support rod is covered by the corresponding louver.

[0027] In one embodiment, the louvered frame is a one-piece molded part.

[0031] In the aforementioned air handling unit, the air outlet channel formed between two adjacent louvers extends parallel to the air guide zone. Since the air outlet side of each louver is an arc convex towards the air outlet side, and the envelope of all air outlet sides is also an arc convex towards the air outlet side, air can be discharged not only in multiple directions parallel to the air outlet channel (multiple directions within the included angle range of the air outlet sides), but also in directions intersecting the extended plane of the air outlet channel (towards both sides in a second direction). Compared to existing technologies, this air handling unit not only has a wider air outlet angle in the direction parallel to the air outlet channel, but also allows air to be discharged in the direction intersecting the air outlet channel as it exits, resulting in a wider air outlet range. Simultaneously, the unit body can rotate relative to the base, further expanding the air outlet range. Attached Figure Description

[0072] Please refer to Figures 1 to 4 , Figure 18 An air handling device provided in one embodiment of this application includes a base 700, a body 200, and an air outlet device 100. The body 200 has a mounting opening. The air outlet device 100 is mounted to the mounting opening. The air outlet device 100 includes a louvered frame 110 and a plurality of louvers 120 rotatably mounted on the louvered frame 110. The louvered frame 110 surrounds an air outlet 110a, and the louvered frame 110 has an air inlet side 110b and an air outlet side 110c arranged opposite each other along a first direction X. The air outlet 110a connects the air inlet side 110b and the air outlet side 110c. The plurality of louvers 120 are spaced apart along a second direction Y perpendicular to the first direction X, and each louver 120 includes an air outlet side 120b facing the air outlet side. Each air outlet side 120b has a projection in the second direction Y that is an arc protruding toward the air outlet side 110c, and the envelope of all air outlet sides 120b is an arc protruding toward the air outlet side 110c. The air handling equipment also includes a drive assembly 130, which includes a power source and a pivot shaft 133 driven by the power source to reciprocate at least along the second direction Y. The pivot shaft 133 is disposed on the air inlet side 110b, and the louvers 120 are rotatably connected to the pivot shaft 133 to rotate synchronously under the drive of the pivot shaft 133.

[0073] In the aforementioned air handling equipment, the air outlet channel formed between two adjacent louvers 120 extends in a direction parallel to the air guide zone 120a. Since the air outlet side 120b of each louver 120 is an arc-shaped protrusion away from the air inlet side 110b, air can be discharged in multiple directions parallel to the air outlet channel (multiple directions within the included angle range of the air outlet side 120b). Furthermore, the envelope surface of all air outlet sides 120b is an arc-shaped surface convex towards the air outlet side 110c, meaning that adjacent louvers 120 have different extension lengths towards the air outlet side 110c in the Y direction. This results in differences in the airflow guiding ability of adjacent louvers 120, allowing airflow to also be discharged in a direction intersecting the extension plane of the air outlet channel. In addition, by providing the drive assembly 130, the angle of the louvers 120 can be easily adjusted to regulate the air outlet direction. Meanwhile, the reciprocating movement of the pivot shaft 133 in the second direction Y drives multiple louvers 120 to move synchronously relative to the louver frame 110, occupying only the movement space in the second direction Y. This reduces the space occupied by the pivot shaft 133, thereby reducing the space occupied by the air outlet device 100 and helping to improve the structural compactness of the air handling equipment.

[0074] It should be understood that air handling equipment may also include non-rotating louvers (such as...) Figure 7 Alternatively, all the louvers can be rotated, which will not be elaborated here.

[0075] In this application, when the air handling unit is in use and vertical airflow is directed, the first direction X corresponds to the opening orientation of the mounting port, the second direction Y corresponds to the height direction of the air handling unit, and the third direction Z corresponds to the extension direction of the louvers. The circumferential direction of the unit body 200 is the direction surrounding the second direction Y.

[0076] Air handling equipment can be a heater, dehumidifier, air purifier, air humidifier, air conditioner, water fan, etc., or a device with at least two of the following functions: heating, dehumidification, purification, and humidification.

[0077] Preferably, the air guide zone 120a is planar. This results in lower air resistance and ease of manufacturing. Of course, the air guide zone 120a can also have other structures, such as a curved surface.

[0078] Please refer to Figure 5 and Figure 6The louver frame 110 includes two sides 110f disposed opposite each other in a third direction Z perpendicular to the first direction X and the second direction Y. Each side 110f has a first connecting hole 110d evenly distributed for each louver 120. The louver 120 includes a mounting area 120c at both ends and an air guiding area 120a between the mounting areas 120c. A first rotating shaft 121 extending along the third direction Z is provided in the mounting area 120c. The first rotating shaft 121 is rotatably inserted into the corresponding first connecting hole 110d. The line connecting the plurality of first connecting holes 110d located at least in the middle of any side of the louver frame 110 forms an arc shape protruding toward the air outlet side 110c. In other words, in the embodiments of this application, by arranging the installation positions of each louver 120 on the louver frame 110 in an arc shape, the protrusion distance of each louver 120 relative to the air inlet side 110b (here, each louver 120 refers to the same position on the air inlet side 110b) is different. Combined with the fact that the air outlet side 120b itself has a curvature, the purpose is to achieve the goal of making the envelope surface of the air outlet side 120b of all louvers 120 an arc-shaped surface. At this time, it helps to reduce the processing cost of the louvers 120 and the uniformity of air outlet, and improves the aesthetics of the air handling equipment. It should be understood that the first rotating shaft 121 can also be constructed on the louver frame 110, and correspondingly, the first connecting hole 110d is constructed on the louver 120.

[0079] In one embodiment, the widths of the air-guiding zones 120a of the same louver 120 are substantially equal. This simplifies the structure of the louver 120, facilitates manufacturing, and does not affect the air-guiding performance of the louver 120.

[0080] Please refer to Figure 8 and Figure 9 At least a portion of the air guide zone 120a of the louvers 120 also includes an air inlet side 120d located on the opposite side of the air outlet side 120b, the air inlet side 120d being arc-shaped and convex toward the air outlet side 110c. This structure reduces the width of the air guide zone 120a of the louvers 120. When the louvers 120 are adjusted to their extreme angles, the smaller width of the air guide zone 120a has less impact on the spacing between the louvers 120. Thus, not only is the air outlet direction adjusted, but the air outlet size is almost unaffected. In one specific embodiment, the distance between adjacent louvers 120 is between 10mm and 13mm; the width of the air guide zone 120a is between 14mm and 16mm; and the rotation angle of the louvers 120, with reference to the second direction Y, ranges from 50 degrees to 130 degrees. This structure ensures that adjusting the louvers 120 to their extreme angles has virtually no impact on the air outlet size.

[0081] Further, please refer to Figure 8The width L of the air guide zone 120a of each louver 120 is equal. This not only reduces the processing cost of the louvers 120 but also ensures that the air resistance of each air outlet channel is basically consistent, helping to guarantee uniform airflow. For example... Figure 7 As shown, in practical applications, the width L of the air guide zone 120a is the dimension in the first direction X.

[0082] Of course, in other embodiments, the widths of each louver 120 may also be different from each other. This can set all the first connecting holes 110d on each side 110f to be on a straight line, so that the envelope surface of the air outlet side 120b of each louver 120 forms an arc surface. This is easy to understand for those skilled in the art, and will not be elaborated here.

[0083] In the above embodiment, each louver 120 is assembled onto the first connecting hole 110d on the side 110f via the first pivot 121 on its mounting area 120c. This not only makes the structure simple and easy to manufacture, but also reduces the obstruction of the air outlet channel and air outlet by other structures in the louver frame 110 used for mounting the louvers 120, which helps to improve energy efficiency.

[0084] Please refer to Figure 5 Each side 110f of the louver 110 also has multiple guide grooves 110e. One end of each guide groove 110e is connected to a first connecting hole 110d, and the other end is arranged through the air outlet side 110c in a direction parallel to the first direction X. The depth of the guide groove 110e is less than the depth of the first connecting hole 110d. When actually installing the louver 120, the first rotating shaft 121 on the louver 120 is inserted into the first connecting hole 110d through the guide groove 110e, which facilitates the installation and removal of the louver 120.

[0085] Still refer to Figure 5 The louver frame 110 also includes two top edges 110g disposed opposite each other in the second direction Y. The top edges 110g and the corresponding side edges 110f are connected by a connecting portion 110f2. The outer edge 110f3 of the connecting portion 110f2 forms an arc transition between the top edges 110g and the corresponding side edges 110f. This facilitates the formation of the louver frame 110 into a rounded rectangle shape, achieving a reduction in the size of the louver frame 110 without significantly affecting the airflow of the air handling equipment. This reduces the space occupied by the louver frame 110 in the air handling equipment body 200, contributing to a more compact overall structure of the air handling equipment. It should be understood that in this application, "rounded rectangle" does not necessarily mean a perfect circle; it can also be other smooth arcs, such as elliptical arcs.

[0086] Continue to refer to Figure 5The inner edge 110f4 of the connecting portion 110f2 is formed by connecting multiple steps 110f21 in sequence. This structure makes the connecting portion 110f2, formed by the multiple steps 110f21, stable and less prone to deformation, thus improving the stability of the louver frame 110. Of course, in other embodiments, the connecting portion 110f2 can also be arc-shaped, as long as the louver frame 110 can be a rounded rectangle.

[0087] At least a portion of the vertical surface of step 110f21 (i.e., the side surface of the step along the second direction Y) is used for mounting louvers 120. For example, at least a portion of the vertical surface of step 110f21 has a first connecting hole 110d formed therein, and the first pivot 121 of the corresponding louver 120 (e.g., the louvers at the upper and lower ends along the second direction Y) is rotatably inserted into the first connecting hole 110d on the vertical surface of the corresponding step 110f21. In this way, the height of step 110f21 provides rotation space for the corresponding louver 120, thereby allowing for convenient adjustment of the orientation of these louvers 120.

[0088] In an optional embodiment, refer to Figure 5 The top edge 110g includes a straight section 110g1 and two curved sections 110g2 at both ends of the straight section 110g1, each curved section 110g2 being connected to an adjacent connecting portion 110f2. This further helps to construct the louver frame 110 as a rounded rectangle.

[0089] For specific implementation examples, please refer to Figure 8 and Figure 9 In each louver 120, a second rotating shaft 122 is disposed in an installation area 120c offset from the first rotating shaft 121. Multiple second connecting holes 133a are provided on the pivot shaft 133, and the second rotating shaft 122 is rotatably inserted into the corresponding second connecting hole 133a. This achieves a rotatable connection between the pivot shaft 133 and the louver 120, resulting in a simple structure and low manufacturing cost.

[0090] It should be understood that the second rotating shaft 122 can also be constructed on the pivot shaft 133, and correspondingly, the second connecting hole 133a is constructed on the louver 120.

[0091] In some embodiments, please refer to Figure 8 and Figure 9Each louver 120 has a mounting area 120c with a widened portion 123 extending toward the air inlet side 110b, and a second rotating shaft 122 is mounted on the widened portion 123. By constructing the widened portion 123 on the louver 120, not only is the strength of the louver 120 improved, but the installation of the second rotating shaft 122 is also facilitated. Furthermore, by constructing the widened portion 123, the distance between the second rotating shaft 122 and the first rotating shaft 121 becomes larger, resulting in a larger torque applied to the second rotating shaft 122, thus allowing the louvers 120 to be rotated with less force.

[0092] In one embodiment, see Figure 8 and Figure 9 The widened portion 123 has a hollowed-out portion 124. The hollowed-out portion 124 can be a hollowed-out hole or a hollowed-out notch, whichever is more specific. The hollowed-out portion 124 can reduce the weight of the louver 120 and ensure the balance of the rotation of the louver 120.

[0093] Please see Figures 11 to 14 The pivot shaft 133 includes a first connecting rod 1331 extending along a second direction Y, and at least a portion of a second connecting hole 133a is formed on the first connecting rod 1331. This type of pivot shaft 133 has a simple structure, is easy to manufacture, and occupies very little space, which helps to miniaturize air handling equipment.

[0094] The first connecting rod 1331 is adjacent to one side 110f of the louver frame 110, and its end is formed into an arc-shaped bend that matches the connecting portion 110f2. In this way, when the pivot shaft 133 (or the first connecting rod 1331) reciprocates along the second direction Y, it will not interfere with the movement of the louver frame 110, thereby allowing for smooth adjustment of the orientation of the louver 120.

[0095] In another embodiment, the pivot shaft 133 further includes a second connecting rod 1332 extending along a second direction Y. The second connecting rod 1332 is spaced apart from the first connecting rod 1331 along a third direction Z and moves synchronously. At least a portion of the second connecting hole 133a is provided on the second connecting rod 1332. This facilitates connecting the louver to the first connecting rod 1331 and the second connecting rod 1332.

[0096] Preferably, the first connecting rod 1331 and the second connecting rod 1332 are connected end to end to form a frame 84. In this case, the pivot shaft 133 forms a frame structure, which is lightweight, high-strength, and not easily deformed.

[0097] Please refer to Figure 15The louvered frame 110 has an air inlet side 110b with a limiting recess 110h recessed towards the air outlet side 110c. The pivot shaft 133 is slidably disposed in the limiting recess 110h and can reciprocate within the limiting recess 110h in a direction parallel to the second direction Y. When using the air handling equipment, the limiting recess 110h limits the extreme position of the pivot shaft 133 on both sides in the second direction Y to prevent the pivot shaft 133 from moving excessively and becoming difficult to return to its original position. When an external force drives the force-receiving member 131 to control the pivot shaft 133 to move to the extreme position and cannot move further, the external force cannot rotate the force-receiving member 131, indicating that the force-receiving member 131 has rotated to the correct position and the external force can be removed. At this time, the limiting recess 110h is used to determine the movement limit of the entire power, resulting in a simple and reliable structure. Furthermore, the limiting walls help maintain the shape of the frame 84, further preventing deformation or positional displacement of the frame 84.

[0098] Please see Figure 11 and Figure 15 Please refer to the following: Figure 8 and Figure 9The first connecting rod 1331 is disposed near the side 110f of the louver frame 110, and the second connecting rod 1332 is disposed corresponding to the middle of the louver frame 110. The second pivot 122 of the first and last louvers 120 in the second direction Y is rotatably inserted into the second connecting hole 133a on the second connecting rod 1332; the second pivot 122 of the remaining louvers 120 is rotatably inserted into the second connecting hole 133a on the first connecting rod 1331. Specifically, the second pivot 122 of the first and last louvers 120 in the second direction Y is located at the inner end 1231 of the widened portion 123, and the corresponding second connecting hole 133a is disposed on the second connecting rod 1332. The second pivot 122 of the remaining louvers 120 is located at the outer end 1232 of the widened portion 123, and the corresponding second connecting hole 133a is disposed on the first connecting rod 1331. In this application, the end of the widened portion 123 facing away from the side 110f of the louver frame 110 is its inner end, and the end of the widened portion 123 facing the side 110f of the louver frame 110 is its outer end. At this time, the first and last louvers 120 are supported on the first connecting rod 1331, and the remaining louvers 120 are supported on the second connecting rod 1332. This allows the pivot shaft 133 to be subjected to more even force, further preventing deformation or misalignment of the pivot shaft 133. For the pivot shaft 133 forming the frame 84, this also helps prevent deformation or misalignment of the frame 84. Furthermore, the line connecting the plurality of second connecting holes 133a on the first connecting rod 1331 forms the same arc shape as the line connecting the first connecting holes 110d. In this way, the first pivot 121 and the second pivot 122 of the louver 120 can be conveniently inserted into the first connecting hole 110d and the second connecting hole 133a of the first connecting rod 1331 on the louver frame 110, and the louver 120 will not be twisted.

[0099] Of course, in other embodiments, all the second connecting holes 133a can be provided on the second connecting rod 1332 or the first connecting rod 1331, as long as the strength is sufficient.

[0100] In the above embodiment, the second rotating shaft 122 is located on the louver 120, and the second connecting hole 133a is located on the pivot shaft 133 to realize the rotatable connection between the louver 120 and the pivot shaft 133. Of course, a shaft can also be provided on the pivot shaft 133, and a hole rotatably connected to the shaft can be provided on the louver 120 to realize the rotatable connection between the two.

[0101] In one embodiment, see Figure 12The louver frame 110 includes a frame body 111 and support bars 112, which are compliantly and spaced apart between the two sides 110f (i.e., the support bars 112 are connected between the two top edges 110g) to help maintain the shape of the louver frame 110. The support bars 112 have multiple support grooves 1121, in which each louver 120 is rotatably supported to maintain its shape and prevent deformation due to uneven force when the louvers 120 rotate. Furthermore, the projection of the first connecting rod 1331 onto the louver frame 110 is within the range of the frame body 111 (e.g., one side 110f), and the projection of the second connecting rod 1332 onto the louver frame 110 is within the range of the support bars 112. This allows for the obstruction of the first and second connecting rods 1331 and 1332, preventing them from being seen from the air outlet side 110c and improving aesthetics.

[0102] Along the second direction Y, the pivot 133 is defined between the support bar 112 and a side 110f. This ensures that the pivot 133 (e.g., frame 84) can move along the second direction Y, thereby allowing the user to smoothly adjust the orientation of the louvers.

[0103] In some embodiments, please refer to Figure 13 and Figure 14 The pivot shaft 133 in the frame form also includes a plurality of inner support rods 1333 connected between the first connecting rod 1331 and the second connecting rod 1332, with the inner support rods 1333 spaced apart. In this case, the inner support rods 1333 can improve the overall strength of the frame 84 and prevent accidental deformation of the frame 84. In a specific embodiment, the inner support rods 1333 are integrally formed with the first connecting rod 1331 and the second connecting rod 1332. Furthermore, when the frame 84 is assembled onto the louver frame 110, the inner support rods 1333 are correspondingly arranged with the louvers 120 and are covered by the corresponding louvers 120. Therefore, the inner support rods 1333 are not visible from the air outlet side 110c, and thus do not obstruct airflow, improving the aesthetics of the air outlet device 100 and the user experience.

[0104] In some embodiments, see Figure 10 and Figure 16 The power source includes a force-receiving component 131 and a transmission part 132. The transmission part 132 connects the force-receiving component 131 and the pivot shaft 133. The force-receiving component 131 is controlled to drive the pivot shaft 133 to reciprocate in a direction parallel to the second direction Y via the transmission part 132.

[0105] Please refer to Figure 10 and Figure 16 Please refer to the following: Figures 11 to 15The force-receiving component 131 is rotatable relative to the body 200. The transmission unit 132 includes a rocker arm 1323 connected to the force-receiving component 131 and a connecting rod 1321 connected to the rocker arm 1323. The force-receiving component 131 drives the rocker arm 1323 to rotate. Specifically, the rocker arm 1323 has a second strip-shaped hole 1323a. One end of the connecting rod 1321 is rotatably disposed in the second strip-shaped hole 1323a and can move along the second strip-shaped hole 1323a. The other end of the connecting rod 1321 has a first strip-shaped hole 1321a and a hinge hole. A rotating shaft that mates with the hinge hole is constructed on the louver frame 110, and a rotating shaft that mates with the first strip-shaped hole 1321a is also constructed on the drive frame.

[0106] When an external force is applied to the force-bearing component 131, causing it to rotate, the rocker arm 1323 swings accordingly, and the connecting rod 1321 rotates relative to the louver frame 110 through the hinge hole. As the connecting rod 1321 rotates, its other end engages with the pivot shaft 113 through the second slot 1323a, causing the pivot shaft 133 to reciprocate in the second direction Y. This achieves the movement of the pivot shaft 133. Furthermore, as the connecting rod 1321 rotates, its end within the second slot 1323a moves along the second slot 1323a to accommodate the distance between the rocker arm 1323 and the louver frame 110.

[0107] The specific construction of the connecting rod 1321 is not specifically limited, as long as it has the above-mentioned characteristics.

[0108] In a preferred embodiment, please refer to Figure 17 A rotating shaft is provided on the body 200, and a pivot hole 1323c is provided in the middle of the rocker arm 1323 to rotatably connect the rocker arm 1323 to the rotating shaft. A second strip-shaped hole 1323a and a third strip-shaped hole 1323b are constructed at both ends of the rocker arm 1323 (i.e., on both sides of the pivot hole 1323c). A connecting shaft 1311 is provided on the force-bearing member 131, and the connecting shaft 1311 is movably engaged in the third strip-shaped hole 1323b.

[0109] When it is necessary to adjust the orientation of the louvers 120 to regulate the airflow direction, the force-bearing component 131 is rotated, and the connecting shaft 1311 rotates accordingly. This rotation drives the rocker arm 1323 to rotate accordingly through the third strip hole 1323b. The rocker arm 1323 rotates around the second strip hole 1323a and drives the connecting rod 1321 to rotate. As a result, the frame (or pivot shaft 133) reciprocates in the second direction Y to drive multiple louvers 120 to rotate synchronously relative to the louver frame 110, thereby realizing the adjustment of the orientation of the louvers 120 and the regulation of the airflow direction.

[0110] In some embodiments, referring to 1, a decorative ring 150 is also installed on the air outlet 110a, and cut-off portions are provided at both ends of the air outlet side 120b to form a clearance area 120e to cooperate with the decorative ring 150. When using the air handling equipment, the clearance area 120e avoids interference between the louvers 120 and the decorative ring 150 when they rotate, thereby making the rotation of the louvers 120 smoother and improving the user experience.

[0111] Furthermore, a light guide ring 140 is fitted onto the outer side of the decorative ring 150. The light guide ring 140 contains a light strip capable of emitting multiple colors of light, allowing the air handling equipment equipped with the air outlet device 100 to emit different colors of light in different operating modes to alert the user.

[0112] In some embodiments, the louver frame 110 is a one-piece molded component. This facilitates manufacturing and provides better structural strength.

[0113] In some embodiments, please refer to Figure 1 , Figure 18 , Figure 19 and Figure 21 The air handling unit 200 houses a filter assembly 400 and a fan assembly. A heating assembly 500 is also located at the mounting port to heat the airflow exiting the outlet 110a when needed, creating a hot airflow. In one specific embodiment, the heating assembly 500 is enclosed by the outlet device 100 to prevent external contact with the heating assembly 500, thereby improving the safety of the air handling unit. Furthermore, the air handling unit includes a humidifier assembly 600. The humidifier assembly 600 humidifies the air to provide a comfortable humidity level for the user.

[0114] When using the air handling unit, outside air is drawn in through the air inlet of the unit 200 by the fan assembly, passes through the filter assembly 400 and the main air duct 300, and is then discharged to the outside through the air outlet 100. The air handling unit has multiple operating modes. In air purification mode, only the filter assembly 400 and the fan assembly are activated to purify the air. In warm air mode, the filter assembly 400, the fan assembly, and the heating assembly 500 are all activated to purify and heat the air. In humidification mode only, the humidification assembly 600 generates atomized water vapor, which is discharged to the outside through the mist outlet. In humidification and purification mode, the atomizing assembly 600, the filter assembly 400, and the fan assembly are activated, generating clean air while discharging atomized water vapor. In humidification, purification, and heating mode, all components are activated. Thus, the air handling unit offers multiple operating modes to meet various user needs and offers high cost-effectiveness.

[0115] The filter assembly 400 can be a HEAP (High Efficiency Particulate Air Filter) assembly, and the heating assembly 500 can be a PTC (Positive Temperature Coefficient) heating assembly. HEAP and PTC heating assemblies are conventional components in this field and will not be described in detail here.

[0116] In one specific embodiment, please refer to Figure 19 The atomizing assembly 600 includes an atomizing box 601, a mist outlet pipe 603, and a water tank 602. The water tank 602 is positioned above the atomizing box 601, and the mist outlet pipe 603 communicates with and extends upwards from the atomizing box 601 to effectively humidify the air. This separate arrangement of the water tank 602 and the atomizing box 601 effectively utilizes the space of the air handling unit, resulting in a compact structure. Furthermore, with the atomizing box 601 below the water tank 602, water in the water tank 602 can automatically flow into the atomizing box 601 by gravity, eliminating the need for a pump or other power components, which helps reduce the energy consumption of the air handling unit.

[0117] In another embodiment, please refer to Figure 20 The water tank 602 and the atomizing box 601 are connected by a pipe 604. A control valve 605 is installed at the water outlet of the water tank 602 and / or the water inlet of the atomizing box 601. The control valve 605 is controlled to open or close the water outlet of the water tank 602 and the water inlet of the atomizing box 601. Thus, when the water level in the atomizing box 601 is lower than a predetermined level, the control valve 605 is opened to allow water to flow into the atomizing box 601. When the water level in the atomizing box 601 is equal to or higher than the predetermined level, the control valve 605 is closed to prevent water from flowing into the atomizing box 601. This allows for automatic control of the water volume in the atomizing box 601 according to preset requirements, preventing excessive water from flowing into the atomizing box 601 and overflowing, which could damage the air handling equipment.

[0118] In one embodiment, the base 700 includes a rotating assembly, and the unit 200 is mounted on the base 700 and rotated circumferentially by the rotating assembly. This allows for airflow within a 360-degree range. Compared to existing technologies, the aforementioned air handling equipment not only has a wider airflow angle in the direction parallel to the airflow duct, but also allows air to be discharged along the direction intersecting the airflow duct as it leaves the duct, resulting in a wider airflow range. Simultaneously, the rotating configuration of the unit 200 further expands the airflow range.

[0119] Please see Figures 22 to 25The rotating assembly includes a central wheel 702, planetary gears 802, a rotating bracket 803, and a drive component 801. The machine body 200 is mounted on the rotating bracket 803. The central wheel 702 is fixedly connected, and the drive component 801 is fixedly mounted to the rotating bracket 803. The planetary gears 802 mesh with the central wheel 702 and are driven by the drive component 801 to rotate around the central wheel 702, thereby causing the rotating bracket 803 and the machine body 200 to rotate circumferentially. When the machine body 200 rotates, the drive component 801 drives the planetary gears 802 to rotate. When the planetary gears 802 rotate, they rotate around the outer circumference of the central wheel 702, which in turn causes the rotating bracket 803 to rotate relative to the base 700, thus realizing the rotation of the machine body 200.

[0120] Furthermore, the base 700 has a fixedly mounted support frame 701, and the rotating bracket 803 is rotatably supported on the support frame 701. The central wheel 702 is fixed on the support frame 701. In this way, the support frame 701 can form a space for the installation of the central wheel 702 and the planetary gears 802, which facilitates the arrangement of the central wheel 702 and the planetary gears 802.

[0121] Furthermore, the drive component 801 is a motor. This simplifies the overall structure of the machine.

[0122] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0123] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
