[0014] This application provides an air guide structure and an air handling device having the air guide structure. The air guide structure includes a main body, and four guide vanes are disposed in the air guide cavity of the main body. The four guide vanes extend along a first direction and are spaced apart along a third direction to form at least two air ducts in the air guide cavity. The four guide vanes are configured to rotate around a second direction to adjust the air outlet range of the main body, thereby flexibly adjusting the air outlet range and forming continuous airflow at the air outlet to achieve uniform air delivery and continuous blowing.

[0017] The baffle surrounding part of the air inlet can divert the airflow entering the air guide cavity through the air inlet, preventing the air inlet and outlet from being directly connected, reducing airflow noise, and improving the user experience.

[0018] The structural design, in which the distance between the first and second walls of the main body increases from the end closer to the air inlet to the end closer to the air outlet, can create an airflow expansion at the air outlet, increase the air outlet range, and promote indoor air circulation.

[0024] To make the technical solution and beneficial effects of this application more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0025] In some embodiments of this application, an air guide structure 100 is provided, as shown in the reference... Figure 1 The air guiding structure 100 includes: a main body 10 and guide vanes 20.

[0026] Reference Figures 1-2 The main body 10 has an internal air guide cavity 101. The main body 10 includes an air inlet 102 and an air outlet 103, which are arranged opposite each other along the first direction X and communicate with the air guide cavity 101, respectively. (Refer to...) Figure 8 The main body 10 includes a first wall 11 and a second wall 12 arranged opposite each other along a third direction Z, a third wall 13 and a fourth wall 14 arranged opposite each other along a second direction Y, and an end wall 15 intersecting the first direction X. The first wall 11, the third wall 13, the second wall 12 and the fourth wall 14 are connected end to end to form a tetrahedral structure with openings at opposite ends along the first direction X. The end wall 15 covers one end opening of the tetrahedral structure to form the main body 10, and the other end opening of the tetrahedral structure forms an air outlet 103. (Refer to...) Figure 2 Air inlet 102 is located on the third wall 13. The first direction X, the second direction Y, and the third direction Z intersect each other, as detailed below. Figure 1 and Figure 8 In the embodiment shown, the first direction X, the second direction Y, and the third direction Z are orthogonal to each other. The first direction X is parallel to the length direction of the main body 10, the second direction Y is parallel to the thickness direction of the main body 10, and the third direction Z is parallel to the width direction of the main body 10.

[0027] In some other implementations, the air inlet 102 can be opened on the end wall 15 or other wall surfaces. The specific choice can be made according to the actual usage requirements. It is only necessary to ensure that the air inlet 102 and the air outlet 103 are set opposite to each other along the first direction X.

[0028] Reference Figure 2 The guide vanes 20 are disposed in the air guide cavity 101. There are four guide vanes 20, which extend along the first direction X respectively. The four guide vanes 20 are arranged at intervals along the third direction Z to form at least two air ducts 104 in the air guide cavity 101.

[0029] The four guide vanes 20 are configured to rotate around the second direction Y according to the position signal, and the four guide vanes 20 work together to adjust the air outlet range of the air outlet 103.

[0030] Air handling units have a fixed air outlet range and a single air outlet angle, which cannot meet the diverse air outlet needs of users. In order to increase the air outlet range, air handling units usually add an oscillation function. However, the air outlet in oscillation mode can only blow on the user intermittently, creating an annoying intermittent wind sensation and failing to create continuous air outlet, thus affecting the user experience.

[0031] The air guiding structure 100 provided in this application embodiment includes a main body 10, an air guiding cavity 101 inside the main body 10, and an air inlet 102 and an air outlet 103 respectively arranged opposite to each other along the first direction X and communicating with the air guiding cavity 101. At least four guide vanes 20 are provided in the air guiding cavity 101. The guide vanes 20 extend along the first direction X and are arranged at intervals along the third direction Z to form at least two air ducts 104 in the air guiding cavity 101. The four guide vanes 20 are respectively configured to be able to rotate around the second direction Y. By coordinating the rotation of the four guide vanes 20, the air outlet range of the air outlet 103 of the main body 10 is adjusted, thereby flexibly adjusting the air outlet range and forming continuous air outlet at the air outlet 103 to achieve uniform air supply and continuous blowing. This can eliminate the traditional oscillating air supply mode of the air handling device, avoid the intermittent wind feeling caused by the oscillating air supply of the air handling device, promote indoor air circulation, improve user experience, and enhance comfort.

[0032] Furthermore, by adjusting the air outlet range of the air outlet 103 through the rotation of the four guide vanes 20, the airflow discharged from the air outlet 103 can be redirected on the horizontal plane, thereby directing the airflow discharged from the air outlet 103 towards users in different areas within the air outlet range of the air outlet 103. In addition, by controlling the simultaneous oscillation of the four guide vanes 20, oscillation as in a conventional fan can also be achieved.

[0033] Furthermore, the four guide vanes 20, each rotating around the second direction Y, can be coordinated to open or close the air duct 104, thereby achieving multi-zone airflow control. This allows for direct blowing, indirect air supply, or zoned control, and the airflow range of the air outlet 103 can be adjusted according to seasonal temperature changes, providing users with a comfortable experience year-round and enhancing their physical comfort. For example, in seasons when outdoor temperatures are high and cool air is needed, the rotation of the guide vanes 20 ensures that the airflow from the air outlet 103 continuously blows onto the user, avoiding the intermittent wind sensation caused by oscillating airflow and improving comfort. In seasons when outdoor temperatures are low and hot air is needed, the rotation of the guide vanes 20 directs the airflow from the air outlet 103 away from the user, avoiding the discomfort caused by continuous hot air blowing on the user, thus ensuring comfort while increasing indoor temperature. Alternatively, depending on the user's choice, the airflow from the air outlet 103 can be directed towards or away from the user.

[0034] In some embodiments, refer to Figure 2The guide vane 20 includes two ends arranged opposite each other along the first direction X. The end of the guide vane 20 adjacent to the air outlet 103 is the first end 201, and the end of the guide vane 20 adjacent to the air inlet 102 is the second end 202. The four guide vanes 20 are arranged at intervals along the third direction Z. The four guide vanes 20 include a first guide vane 21 and a second guide vane 22 located at both ends of the third direction Z. The rotation directions of the first guide vane 21 and the second guide vane 22 are the same or different, thereby realizing the adjustment of the air outlet range of the air outlet 103.

[0035] In some embodiments, refer to Figure 2 , Figure 5 and Figure 10 The first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 are moved away from each other. Specifically, the first guide vane 21 rotates counterclockwise and the second guide vane 22 rotates clockwise, thereby moving the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 away from each other. This increases the distance between the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 in the third direction Z, thereby relatively increasing the air outlet range of the air outlet 103 and forming a wide-angle air outlet mode. The wide-angle air outlet mode allows the air guide structure 100 to form a continuous wide-angle airflow coverage, achieving uninterrupted airflow, improving the cooling or heating effect, and promoting indoor air circulation and improving air quality.

[0036] In some embodiments, refer to Figure 4 , Figure 7 , Figure 13 and Figure 14 The first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 are brought closer to each other. Specifically, the first guide vane 21 rotates clockwise and the second guide vane 22 rotates counterclockwise, thereby bringing the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 closer to each other, thereby reducing the distance between the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 in the third direction Z, and thus relatively reducing the air outlet range of the air outlet 103.

[0037] Specifically, in Figure 4 and Figure 13 The illustrated embodiment can form a split-flow air outlet mode. Figure 7 and Figure 14 The illustrated embodiment can form a jet-air outlet mode. The split-flow air outlet mode allows the air guide structure 100 to achieve zoned control of the airflow from the air outlet 103, so that the airflow discharged through the air outlet 103 is directed towards different users or avoids users, thereby providing direct airflow to different areas, improving user experience and comfort. The jet-air outlet mode can increase the air velocity from the air outlet 103, thereby increasing the air delivery distance of the air guide structure 100, expanding the air outlet coverage, improving cooling or heating effects, and promoting air circulation.

[0038] In some embodiments, refer to Figure 6 , Figure 11 and Figure 12 The first guide vane 21 and the second guide vane 22 rotate in the same direction. Specifically, the first guide vane 21 and the second guide vane 22 both rotate counterclockwise, or the first guide vane 21 and the second guide vane 22 both rotate clockwise, so that the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 face the same direction, forming a side-blowing air outlet pattern at the air outlet 103.

[0039] Specifically, such as Figure 6 and Figure 11 In the illustrated embodiment, both the first guide vane 21 and the second guide vane 22 rotate counterclockwise, forming a side-blowing airflow pattern with air exiting from the left side. Specifically, as shown... Figure 12 In the illustrated embodiment, both the first guide vane 21 and the second guide vane 22 rotate clockwise to form a side-blowing airflow pattern with air exiting from the right side. This side-blowing airflow pattern allows the airflow guide structure 100 to achieve zoned control of the airflow from the air outlet 103, thereby directing the airflow discharged through the air outlet 103 towards or away from the user, thus providing direct airflow to a specific area, enhancing the user experience, and improving user comfort.

[0040] In some embodiments, a first air duct 1041 is defined between the first guide vane 21 and the first wall 11 of the body 10, and the first guide vane 21 is configured to abut against the first wall 11 to close the first air duct 1041. Specifically, in some implementations, refer to Figure 4 , Figure 7 as well as Figures 12-14 The second end 202 of the first guide vane 21 abuts against the first wall 11 to close the first air duct 1041. In some implementations, refer to... Figures 10-11 The first guide vane 21, located in the middle section between the first end 201 and the second end 202, abuts against the first wall 11 to close the first air duct 1041. In some implementations, the first end 201 of the first guide vane 21 abuts against the first wall 11 to close the first air duct 1041. This application embodiment does not specifically limit the abutment position between the first guide vane 21 and the first wall 11; the specific position can be selected according to actual usage. For example, the length of the first guide vane 21 along the first direction X can be adjusted, as long as it ensures that the first guide vane 21 abuts against the first wall 11 to close the first air duct 1041.

[0041] The first guide vane 21 rotates to abut against the first wall 11 to close the first air duct 1041, which allows the airflow entering the air guide cavity 101 through the air inlet 102 to be discharged from the air outlet 103 through other air ducts 104, thereby adjusting the air outlet 103 air outlet range and enabling the air guide structure 100 to switch between different air outlet modes.

[0042] In some embodiments, a second air duct 1042 is defined between the second guide vane 22 and the second wall 12, and the second guide vane 22 is configured to abut against the second wall 12 to close the second air duct 1042. Specifically, in some implementations, refer to Figure 4 , Figures 6-7 , Figure 11 as well as Figures 13-14 The second end 202 of the second guide vane 22 abuts against the second wall 12 to close the second air duct 1042. In some implementations, refer to... Figure 10 and Figure 12 The second guide vane 22, located in the middle section between the first end 201 and the second end 202, abuts against the second wall 12 to close the second air duct 1042. In some implementations, the first end 201 of the second guide vane 22 abuts against the second wall 12 to close the second air duct 1042. This application embodiment does not specifically limit the abutment position between the second guide vane 22 and the second wall 12; the specific position can be selected according to actual usage. For example, the length of the second guide vane 22 along the first direction X can be adjusted, as long as it ensures that the second guide vane 22 abuts against the second wall 12 to close the second air duct 1042.

[0043] The second guide vane 22 rotates to abut against the second wall 12 to close the second air duct 1042, which allows the airflow entering the air guide cavity 101 through the air inlet 102 to be discharged from the air outlet 103 through other air ducts 104, thereby adjusting the air outlet 103 air outlet range and enabling the air guide structure 100 to switch between different air outlet modes.

[0044] In some embodiments, the four guide vanes 20 include a first guide vane 21 and a second guide vane 22 located at the Z-axis ends, and a third guide vane 23 and a fourth guide vane 24 located between the first guide vane 21 and the second guide vane 22. The third guide vane 23 is adjacent to the first guide vane 21, and the fourth guide vane 24 is adjacent to the second guide vane 22. A third air duct 1043 is defined between the first guide vane 21 and the third guide vane 23, a fourth air duct 1044 is defined between the fourth guide vane 24 and the third guide vane 23, and a fifth air duct 1045 is defined between the third guide vane 23 and the fourth guide vane 24. The design of the four guide vanes can define five air ducts 104 in the air guide cavity 101, and the four guide vanes 20 can form various configurations to ensure the adjustment accuracy of the air outlet range of the air outlet 103.

[0045] In some embodiments, refer to Figure 10The first guide vane 21 and the second guide vane 22 rotate in opposite directions, and the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 are far apart from each other. The first guide vane 21 abuts against the first wall 11 to close the first air duct 1041, and the second guide vane 22 abuts against the second wall 12 to close the second air duct 1042. The first end 201 of the third guide vane 23 and the first end 201 of the fourth guide vane 24 remain stationary. The third air duct 1043, the fourth air duct 1044 and the fifth air duct 1045 are connected. Since the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 are far apart from each other, the distance between them increases, the air outlet 103 has an increased air outlet range, forming a wide-angle air outlet mode.

[0046] In some embodiments, refer to Figure 2 The first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 are far apart from each other, the first end 201 of the third guide vane 23 and the first end 201 of the fourth guide vane 24 are far apart from each other, the first air duct 1041, the second air duct 1042, the third air duct 1043 and the fourth air duct 1044 are connected, and the fifth air duct 1045 is closed, forming a wide-angle air outlet mode.

[0047] In some embodiments, refer to Figure 5 The first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 are far apart from each other, the first end 201 of the third guide vane 23 and the first end 201 of the fourth guide vane 24 are close to each other, the first air duct 1041, the second air duct 1042, the third air duct 1043 and the fourth air duct 1044 are connected, and the fifth air duct 1045 is closed, forming a wide-angle air outlet mode.

[0048] In some embodiments, refer to Figure 13 The first guide vane 21 and the second guide vane 22 rotate in opposite directions, and the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 approach each other. The first guide vane 21 rotates clockwise until the second end 202 abuts against the first wall 11 to close the first air duct 1041. The second guide vane 22 rotates counterclockwise until the second end 202 abuts against the second wall 12 to close the second air duct 1042. The first end 201 of the third guide vane 23 and the first end 201 of the fourth guide vane 24 move away from each other. The second end 202 of the third guide vane 23 abuts against the second end 202 of the fourth guide vane 24 to close the fifth air duct 1045. The third air duct 1043 and the fourth air duct 1044 are connected, and the airflow is discharged from the third air duct 1043 and the fourth air duct 1044 respectively, forming a split air outlet pattern with left and right air outlets.

[0049] In some embodiments, refer to Figure 4The first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 are close to each other, the first end 201 of the third guide vane 23 and the first end 201 of the fourth guide vane 24 are far apart from each other, the first air duct 1041, the second air duct 1042 and the fifth air duct 1045 are closed, the third air duct 1043 and the fourth air duct 1044 are connected, and the airflow is discharged from the third air duct 1043 and the fourth air duct 1044 respectively, forming a split air outlet mode with left and right air outlets.

[0050] In some embodiments, refer to Figure 4 and Figure 14 The first end 201 of the third guide vane 201 and the first end 201 of the fourth guide vane 24 extend to the air outlet 103 respectively to prevent the airflow in the third air duct 1043 and the fourth air duct 1044 from entering the fifth air duct 1045, thus ensuring the air outlet effect.

[0051] In some embodiments, the first end 201 of the first guide vane 21 and the first end 201 of the second guide vane 22 are close to each other, the third guide vane 23 and the fourth guide vane 24 remain stationary, the first air duct 1041 and the second air duct 1042 are closed, and the third air duct 1043, the fourth air duct 1044 and the fifth air duct 1045 are open to form a jet air outlet mode.

[0054] In some embodiments, refer to Figure 11The first guide vane 21, the second guide vane 22, the third guide vane 23 and the fourth guide vane 24 rotate in the same direction. Specifically, the first guide vane 21, the second guide vane 22, the third guide vane 23 and the fourth guide vane 24 all rotate counterclockwise.

The second end 202 of the second guide vane 22 abuts against the second wall 12 to close the second air duct 1042. The third air duct 1043, the fourth air duct 1044 and the fifth air duct 1045 are open, forming a side-blowing air outlet mode with air outlet on the left side.

[0055] In some embodiments, refer to Figure 12 The first guide vane 21, the second guide vane 22, the third guide vane 23 and the fourth guide vane 24 all rotate clockwise. The second end 202 of the first guide vane 21 abuts against the first wall 11 to close the first air duct 1041.

The third air duct 1043, the fourth air duct 1044 and the fifth air duct 1045 are open, forming a side-blowing air outlet mode with air outlet on the right side.

[0056] In some embodiments, refer to Figure 6 The first guide vane 21, the second guide vane 22, the third guide vane 23 and the fourth guide vane 24 all rotate counterclockwise. The second end 202 of the second guide vane 22 abuts against the second wall 12 to close the second air duct 1042. The first air duct 1041, the third air duct 1043 and the fourth air duct 1044 are open, and the fifth air duct 1045 is closed, forming a side-blowing air outlet mode with air outlet on the left side.

[0057] In some embodiments, the first guide vane 21, the second guide vane 22, the third guide vane 23 and the fourth guide vane 24 all rotate clockwise. The second end 202 of the first guide vane 21 abuts against the first wall 11 to close the first air duct 1041, the second air duct 1042, the third air duct 1043 and the fourth air duct 1044 are open, and the fifth air duct 1045 is closed, forming a side-blowing air outlet mode with air outlet on the right side.

[0058] In some embodiments, the third guide vane 23 is configured to abut against the first guide vane 21 to close the third air duct 1043. Specifically, a side-blowing airflow mode is formed when the first air duct 1041 is closed and any one of the second air duct 1042, the fourth air duct 1044, and the fifth air duct 1045 is open. A side-blowing airflow mode is formed when the first air duct 1041 is open and the second air duct 1042, the fourth air duct 1044, and the fifth air duct 1045 are closed.

[0059] In some embodiments, the fourth guide vane 24 is configured to abut against the second guide vane 22 to close the fourth air duct 1044. Specifically, a side-blowing airflow mode is formed when the second air duct 1042 is closed and any one of the first air duct 1041, the third air duct 1043, and the fifth air duct 1045 is open. A side-blowing airflow mode is formed when the second air duct 1042 is open and the first air duct 1041, the third air duct 1043, and the fifth air duct 1045 are closed.

[0060] In some embodiments, the number of guide vanes 20 can be more than four. For example, an additional guide vane 20 can be added between the first guide vane 21 and the third guide vane 23, and / or an additional guide vane 20 can be added between the second guide vane 22 and the fourth guide vane 24. The specific selection can be made according to the actual application.

[0061] In some embodiments, the guide vane 20 abuts against the third wall 13 of the main body 10 along the second direction Y, thereby avoiding a gap between the guide vane 20 and the third wall 13 in the second direction Y, and thus preventing the airflow in one of the two adjacent air ducts 104 from flowing into the other adjacent air duct 104 due to the gap between the guide vane 20 and the third wall 13, ensuring that the airflow entering the air guide cavity 101 can be discharged from the designated air duct 104, and ensuring the accuracy of adjusting the air outlet range of the air outlet 103.

[0062] In some embodiments, the guide vane 20 is provided with an abutment portion (not shown in the figure) protruding from the side of the third wall 13 along the second direction Y. The guide vane 20 abuts against the third wall 13 through the abutment portion, which is configured to fill the gap between the guide vane 20 and the third wall 13.

[0063] In some embodiments, the abutment portion is made of soft bristles or rubber.

[0064] In some embodiments, the air guide structure 100 further includes a first plate (not shown in the figure) and a second plate (not shown in the figure) disposed on the outside of the main body 10.

[0065] A first plate is disposed on one end of the third wall 13 along the first direction X, adjacent to the air outlet 103. The first plate and the third wall 13 are stacked along the second direction Y. The first plate is configured to be movable along the second direction Y, so that the first plate moves closer to or away from the third wall 13. A second plate is disposed on one end of the fourth wall 14 along the first direction X, adjacent to the air outlet 103. The second plate and the fourth wall 14 are stacked along the second direction Y. The second plate is configured to be movable along the second direction Y, so that the second plate moves closer to or away from the fourth wall 14.

[0066] The structural design, in which the first and second plates can move along the second direction Y, allows the first and second plates to work together to redirect the airflow discharged from the air outlet 103 in the vertical plane, thereby enabling the airflow discharged from the air outlet 103 to cover target areas at different heights. The movement of the first and second plates along the second direction Y also allows for vertical oscillation.

[0067] In some embodiments, along the first direction X, the end of the first plate away from the air outlet 103 is fixedly connected to the third wall 13, and the end of the first plate adjacent to the air outlet 103 can rotate relative to the third wall 13 around the third direction Z, so that the end of the first plate adjacent to the air outlet 103 moves closer to or further away from the third wall 13. Along the first direction X, the end of the second plate away from the air outlet 103 is fixedly connected to the fourth wall 14, and the end of the second plate adjacent to the air outlet 103 can rotate relative to the fourth wall 14 around the third direction Z, so that the end of the second plate adjacent to the air outlet 103 moves closer to or further away from the fourth wall 14. This allows the ends of the first plate adjacent to the air outlet 103 and the second plate adjacent to the air outlet 103 to move closer to or further away from each other along the second direction Y, thus adjusting the air outlet range of the air outlet 103 in the vertical plane.

[0068] In some embodiments, the third wall 13 includes a first segment and a second segment connected along a first direction X, the first segment being adjacent to the air outlet 103, and the first segment being configured to be movable relative to the second segment along a second direction Y. The fourth wall 14 includes a third segment and a fourth segment connected along the first direction X, the third segment being adjacent to the air outlet 103, and the third segment being configured to be movable relative to the fourth segment along the second direction Y. The structural design that allows the first and third segments to be movable along the second direction Y can change the redirection of the airflow discharged from the air outlet 103 in the vertical plane, thereby enabling the airflow discharge range of the air outlet 103 to cover target areas at different heights.

[0069] In some embodiments, the first segment is configured to rotate relative to the second segment along a third direction Z, and the third segment is configured to rotate relative to the fourth segment along a third direction Z, so that the first segment and the third segment can move closer to each other or further away from each other along the second direction Y, thereby adjusting the air outlet range of the air outlet 103 in the vertical plane.

[0070] In some embodiments, refer to Figure 1The air guide structure 100 also includes a detector 30 disposed on the outer side of the main body 10. The detector 30 is configured to detect the position of a user located around the air guide structure 100 and generate a position signal. The placement of the detector 30 ensures that the airflow discharged through the air outlet 103 accurately faces or avoids the user's location. Furthermore, it can adjust the airflow discharged from the air outlet 103 according to seasonal temperature changes, providing a comfortable experience for the user year-round. For example, in seasons when outdoor temperatures are high and cool air is needed, the rotation of the guide vanes 20 can direct the airflow discharged from the air outlet 103 towards the user's location, thus creating a continuous breeze for the user and avoiding the intermittent wind sensation caused by oscillating airflow, thereby improving comfort. In seasons when outdoor temperatures are low and warm air is needed, the rotation of the guide vanes 20 can direct the airflow discharged from the air outlet 103 away from the user's location, thus avoiding the discomfort caused by continuous hot air blowing on the user, ensuring comfort while increasing indoor temperature. Alternatively, depending on the user's choice, the airflow discharged from the air outlet 103 can be directed toward or away from the user's location.

[0071] In some embodiments, the detector 30 is an infrared detector or a radar. This application does not limit the specific type of the detector 30, as long as it can detect the user's location. The location signal includes the user's coordinate information.

[0072] In some embodiments, refer to Figure 1 and Figure 3 The air guiding structure 100 also includes a pipe body 40, which extends along the second direction Y and is connected to the main body 10 along the second direction Y. One end of the pipe body 40 is bent along the first direction X toward the adjacent end wall 15 to form a bent section 41. The pipe body 40 is connected to the main body 10 through the bent section 41 and communicates with the air inlet 102 through the bent section 41. The end of the pipe body 40 facing away from the main body 10 along the second direction Y is configured to face the air outlet of the air handling device. The airflow generated by the air handling device enters the pipe body 40 through the air outlet and enters the air guiding cavity 101 of the main body 10 through the pipe body 40 and the air inlet 102. The structural design of the bent section 41 on the pipe body 40 can extend the air intake path of the airflow discharged through the air outlet into the air guiding cavity 101, thereby reducing the intake noise of the air guiding structure 100, and further reducing the exhaust noise, thus improving the user experience.

[0073] In some embodiments, refer to Figure 1 The detector 30 is disposed on the side of the pipe body 40 adjacent to the air outlet 103 along the first direction X, and the direction of the detector end of the detector 30 is the same as the direction of the air outlet 103.

[0074] In some embodiments, refer to Figure 2as well as Figures 4-7 The third guide vane 23 includes a first rotating section 231 and a first fixed section 232 connected along a first direction X. The first rotating section 231 is configured to rotate about a second direction Y. Specifically, the first rotating section 231 is configured to rotate relative to the first fixed section 232. The first guide vane 21 is configured to abut against the first fixed section 232 to close the third channel 1043, thereby adjusting the air outlet range of the air outlet 103. The cooperative design of the first rotating section 231 and the first fixed section 232 allows the first rotating section 231 to adjust the air outlet range of the air outlet 103, while the first fixed section 232 strengthens the overall strength of the third guide vane 23 and ensures the rotational stability of the first rotating section 231.

[0075] In some embodiments, refer to Figure 2 as well as Figures 4-7 The fourth guide vane 24 includes a second rotating section 241 and a second fixed section 242 connected along a first direction X. The second rotating section 241 is configured to rotate about a second direction Y. Specifically, the second rotating section 241 is configured to rotate relative to the second fixed section 242. The first guide vane 21 is configured to abut against the second fixed section 242 to close the fourth channel 1044, thereby adjusting the air outlet range of the air outlet 103. The cooperative design of the second rotating section 241 and the second fixed section 242 allows the second rotating section 241 to adjust the air outlet range of the air outlet 103, while the second fixed section 242 strengthens the overall strength of the fourth guide vane 24 and ensures the rotational stability of the second rotating section 241.

[0076] In some embodiments, refer to Figures 2-7 The air guiding structure 100 also includes a baffle 50, which is disposed in the air guiding cavity 101, adjacent to the air inlet 102 and located between the first fixed section 232 and the second fixed section 242. The baffle 50 is configured to surround a portion of the air inlet 102 along its circumferential direction. One end of the first fixed section 232 adjacent to the air inlet 102 and one end of the second fixed section 242 adjacent to the air inlet 102 are respectively connected to the baffle 50 to close the fifth air duct 1045 defined between the third guide vane 23 and the fourth guide vane 24. The cooperative design of the baffle 50 with the first fixed section 232 and the second fixed section 242 forms a closure of the fifth air duct 1045, thereby diverting the airflow entering the air guiding cavity 101 through the air inlet 102, preventing the air inlet 102 from being directly connected to the air outlet 103, reducing airflow noise, and improving the user experience.

[0077] In some embodiments, refer to Figure 2The baffle 50 includes a body 51 and two connecting sections 52. The two connecting sections 52 include a first connecting section 521 and a second connecting section 522. The first connecting section 521 and the second connecting section 522 extend along a first direction X and are arranged at intervals along a third direction Z. Along the first direction X, the body 51 is located between the air inlet 102 and the air outlet 103. The same end of the first connecting section 521 and the second connecting section 522 are respectively connected to the body 51. The other ends of the first connecting section 521 and the second connecting section 522 face the end wall 15 of the body 10, so that the baffle 50 forms a U-shaped structure and surrounds part of the air inlet 102. The end of the first connecting section 521 away from the body 51 is connected to the first fixed section 232, and the end of the second connecting section 522 away from the body 51 is connected to the second fixed section 242 to close the fifth air duct 1045.

[0078] In some embodiments, refer to Figure 2 A protrusion 151 is provided on the inner surface of the end wall 15, facing the air inlet 102. The protrusion 151 and the baffle 50 are arranged opposite each other along the first direction X. Specifically, the protrusion 151 and the body 51 are arranged opposite each other, and the protrusion 151 and the body 51 are respectively located on both sides of the air inlet 102 along the first direction X. The U-shaped structure of the baffle 50 surrounds part of the air inlet 102, so that the airflow entering the air guide cavity 101 through the air inlet 102 first flows to the end wall 15. The design of the protrusion 151 can split the airflow flowing to the end wall 15, so that the airflow flows to one side to the first air duct 1041 and the third air duct 1043, and to the other side to the second air duct 1042 and the fourth air duct 1044, thereby reducing the noise at the air inlet 102 and improving the user experience.

[0079] In addition, the design of the baffle 50 and the protrusion 151 makes the airflow entering the air guide cavity 101 through the air inlet 102 move away from the air outlet 103 along the first direction X. After being guided by the end wall 15, the first wall 11 and the second wall 12, the airflow moves towards the air outlet 103 along the first direction X. This makes the airflow entering the air guide cavity 101 through the air inlet 102 change direction by 180° before flowing towards the air outlet 103. This reduces the swirling at the air inlet 102, makes the airflow field more uniform, and makes the airflow velocity and airflow pressure more uniform in a small space. This reduces the overall size of the main body 10, reduces manufacturing costs, and reduces space occupancy.

[0080] In some embodiments, refer to Figure 2Along the third direction Z, the distance between the first wall 11 and the second wall 12 is S1 mm. Along the first direction X, the value of S1 increases from the end near the air inlet 102 to the end near the air outlet 103. The structural design that the value of S1 increases from the end near the air inlet 102 to the end near the air outlet 103 allows the main body 10 to form an airflow expansion at the air outlet 103, increasing the air outlet range of the air guiding structure 100 in the wide-angle air outlet mode and the side-blowing air outlet mode, and promoting indoor air circulation.

[0081] In some embodiments, refer to Figure 2 The connection between the end wall 15 and the first wall 11 is arc-shaped, and the connection between the end wall 15 and the second wall 12 is arc-shaped, thus forming an arc-shaped structure at the position of the air duct 104 near the air inlet 102, further extending the airflow path from the air inlet 102 to the air outlet 103 and reducing noise.

[0082] In some embodiments, refer to Figure 2 One end of the first wall 11 near the air outlet 103 bends in a direction away from the second wall 12 along the third direction Z to form a first arc segment. The other end of the second wall 12 near the air outlet 103 bends in a direction away from the first wall 11 along the third direction Z to form a second arc segment. Thus, an arc structure is formed at one end of the first air duct 1041 near the air outlet 103 and an arc structure is formed at one end of the second air duct 1042 near the air outlet 103, which prolongs the air outlet path in the first air duct 1041 and the second air duct 1042 and reduces noise.

[0083] In some embodiments, refer to Figure 2 The third wall 13 protrudes from the end away from the air inlet 102 along the first direction X, forming a first arc-shaped protrusion, as shown in the reference. Figure 1 and Figure 8 The fourth wall 14 protrudes from the end away from the air inlet 102 along the first direction X to form a second arc-shaped protrusion. The design of the first arc-shaped protrusion and the second arc-shaped protrusion, combined with the structural design of the first arc-shaped segment of the first wall 11 and the second arc-shaped segment of the second wall 12, can increase the cross-sectional area of ​​the air outlet 103, thereby increasing the air outlet range of the air outlet 103 in the wide-angle air outlet mode.

[0084] In some embodiments, refer to Figure 2 The first fixed section 232 of the third guide vane 23 protrudes from the end away from the first rotating section 231 along the third direction Z, away from the first wall 11, forming a first arc-shaped protrusion. The second fixed section 242 of the fourth guide vane 24 protrudes from the end away from the second rotating section 241 along the third direction Z, close to the second wall 12, forming a second arc-shaped protrusion. The arrangement of the first and second arc-shaped protrusions can further extend the airflow path from the air inlet 102 to the air outlet 103, reducing noise.

[0085] In some embodiments, refer to Figure 3 Along the second direction Y, the distance between the third wall 13 and the fourth wall 14 is S2mm. Along the first direction X, the value of S2 decreases from the end near the air inlet 102 to the end near the air outlet 103. This structural design, where the value of S2 decreases from the end near the air inlet 102 to the end near the air outlet 103, forms a duckbill-shaped air guide structure at the air outlet 103 of the main body 10. This allows the main body 10 to form a jet at the air outlet 103, creating a flat air outlet, increasing the air velocity at the air outlet 103, increasing the air delivery distance, and promoting indoor air circulation.

[0086] In some embodiments, refer to Figure 1 , Figure 3 and Figure 9 The air guiding structure 100 also includes a drive assembly 60, which includes a drive member 61 and a shaft 62 connected to each other. The shaft 62 extends along the second direction Y. The drive member 61 is disposed on the outside of the main body 10, and the shaft 62 is inserted into at least one of the third wall 13 and the fourth wall 14. The guide vane 20 is sleeved on the shaft 62. Specifically, the guide vane 20 is sleeved on the portion of the shaft 62 located inside the air guiding cavity 101. The drive member 61 is configured to drive the shaft 62 to rotate according to the position signal generated by the detector 30, so as to drive the guide vane 20 to rotate around the second direction Y through the shaft 62. The number of guide vanes 20 corresponds one-to-one with the number of drive assemblies 60. The design of the drive assembly 60 can ensure the rotational stability of the guide vane 20 and realize individual control of each guide vane 20, ensuring the accuracy of the rotation angle of the guide vane 20, ensuring the accuracy of the positioning of the guide vane 20, and ensuring the accuracy of the adjustment of the air outlet range of the air outlet 103.

[0087] In some embodiments, the drive element 61 is a motor. The drive element 61 is detachably connected to the third wall 13 of the body 10 via a connecting rod (not shown).

[0088] In some embodiments, the air guide structure 100 further includes indicator lights (not shown in the figure), which are disposed on the fourth wall 14 of the main body 10. The indicator lights are configured to be turned on when the guide vanes 20 rotate to indicate that the guide vanes 20 are rotating. The number of indicator lights corresponds one-to-one with the number of guide vanes 20.

[0089] In some embodiments, the shaft 62 passes through the third wall 13 and the fourth wall 14, one end of the shaft 62 is connected to the drive member 61, and an indicator light is provided at the other end of the shaft 62.

[0090] In some embodiments of this application, an air handling device 200 is provided, with reference to... Figure 15 The air handling unit 200 includes: a body 210 and an air guide structure 100 as described above.

[0091] The body 210 has an air inlet 212 and an air outlet 211 connected to each other. The air guide structure 100 is set at the air outlet 211. The air inlet 102 of the main body 10 faces the air outlet 211. Specifically, the pipe 40 of the air guide structure 100 is set at the air outlet 211. The end of the pipe 40 away from the main body 10 faces the air outlet 211. The airflow discharged from the air outlet 211 enters the air guide cavity 101 of the main body 10 through the pipe 40.

[0092] In this application, the air handling device 200 provided in the embodiment is described using an air purifier as an example. Of course, it is not limited to an air purifier, but can also be an air conditioner, fan, air cooler, or humidifier, etc.

[0093] In some embodiments, refer to Figure 16 The air handling unit 200 also includes a control module 220, which is mounted on the unit body 210. The control module 220 is configured to control the rotation of the guide vanes 20 to adjust the airflow range discharged through the air outlet 103 of the air guide structure 100. The control module 220 can control the rotation direction and angle of the guide vanes 20, allowing the air guide structure 100 to switch between wide-angle air outlet mode, split air outlet mode, side-blowing air outlet mode, and jet air outlet mode. This flexibly adjusts the air outlet range, creating continuous airflow at the air outlet, achieving uniform air delivery and continuous blowing. Compared to traditional oscillating air outlet modes, this avoids the intermittent wind sensation caused by oscillating air outlets, promotes indoor air circulation, improves user experience, and enhances comfort.

[0094] In some embodiments, the control module 220 is configured to control the rotation direction of the guide vane 20 by controlling the rotation direction of the drive member 61.

[0095] In some embodiments, the air guide structure 100 further includes a detector 30, and the drive member 61 and the detector 30 are communicatively connected to the control module 220. The control module 220 is configured to receive a position signal generated by the detector 30 and to control the rotation direction of the drive member 61 according to the position signal, so as to drive the connected guide vane 20 to rotate via the shaft 62, thereby adjusting the air outlet range of the airflow discharged through the air outlet 103 of the air guide structure 100, so that the airflow discharged through the air outlet 103 is directed toward or away from the user's location.

[0096] The control module 220 is equipped with a first command corresponding to the wind following the person and a second command corresponding to the wind avoiding the person. When using the device, the user can select the corresponding command through a remote control (not shown in the figure) that is connected to the control module 220. The control module 220 receives the command selected by the user and controls the drive component 61 to rotate based on the position signal generated by the detector 30, so that the airflow discharged from the air outlet 103 of the air guide structure 100 is directed toward or avoids the user's location.

[0097] The following is an exemplary description of the control method of the air guiding structure 100 in the air handling device 200 provided in the embodiments of this application: The user selects the first command (i.e., the wind follows the user), and the detector 30 detects the user's location and generates a position signal. For example, if the user is at a 45° position to the left of the air outlet 103, the control module 220 receives the position signal and controls the drive component 61 to rotate, causing all four guide vanes 20 to rotate counterclockwise to the desired position. Figure 6 or Figure 11 As shown in the diagram, the air guide structure 100 forms a side-blowing air outlet pattern with air exiting to the left, continuously blowing air towards the user's location. The detector 30 detects that the user has moved to a position 45° to the right of the air outlet 103. After receiving the position signal, the control module 220 controls the drive component 61 to rotate, causing all four guide vanes 20 to rotate clockwise to the side-blowing air outlet pattern with air exiting to the right, thus creating a continuous blowing effect on the user.

[0098] When the user selects the second command (i.e., wind avoidance), the detector 30 detects the user's location and generates a position signal. For example, if the user is at a 45° position to the left of the air outlet 103, the control module 220 receives the position signal and controls the drive component 61 to rotate, causing all four guide vanes 20 to rotate clockwise to a side-blowing air outlet mode to avoid the user's location. Alternatively, if the detector 30 detects the user moving to a 45° position to the right of the air outlet 103, the control module 220 receives the position signal and controls the drive component 61 to rotate, causing all four guide vanes 20 to rotate counterclockwise to a side-blowing air outlet mode to avoid the user's location. Figure 6 or Figure 11 As shown in the arrangement, the air guide structure 100 forms a side-blowing air outlet pattern with the air outlet on the left, in order to avoid the user's location.

[0099] When the user selects the first command, the detector 30 detects that one user is at a 45° position to the left of the air outlet 103 and another user is at a 45° position to the right of the air outlet 103. After receiving the position signals, the control module 220 controls the drive unit 61 to rotate, causing the four guide vanes 20 to rotate to the positions indicated by the command. Figure 4 or Figure 13The airflow splitting mode shown ensures that both users can feel the airflow. When the user selects the second command, the control module 220 receives the position signal and controls the drive unit 61 to rotate, causing the four guide vanes 20 to rotate to positions such as... Figure 7 or Figure 14 The air jet pattern shown is designed to avoid the locations of the two users.
